使用法について
このセンサは最大NA 1.45までの対物レンズに対する光パワー測定をサポートしており、空気中で水や油の液浸媒体を用いた場合でも使用可能です(詳細は「 光学設計」タブをご覧ください)。右上の写真でご覧いただけるように、センサの背面には気体(< 0.95)、水浸(< 1.30)、油浸(< 1.45)と、各条件で推奨する対物レンズのNAが刻印されています。受光面はガラスカバーで保護されています。ガラスカバーは、圧縮空気、またはアセトンやメタノールで湿らせたレンズ用ティッシュで簡単にクリーニングできます。
上の写真でご覧いただけるように、センサの背面にはアライメント用のグリッドがレーザ刻印されています。これは受光面の位置を表しており、ビームのアライメントや集光の際に役立ちます。標準的な正立顕微鏡に使用する場合は、筐体をその刻印面が顕微鏡の対物レンズに対面する向きにして光路に挿入します。パワーセンサの中心が対物レンズの真下にくるように調整したのち、パワー測定ができるようにスライドを反転させてディテクタの受光面をビームに向けます。倒立顕微鏡に使用する場合は、受光面が対物レンズに向くようにディテクタをスライドホルダにセットし、透過照明用ランプの電源を入れます。ビームの位置を刻印されたターゲットの中心に一致させることで、受光面を光路の中心に一致させることができます。
センサの損傷させないために、ビームが集光されない位置にセンサを配置することをお勧めします。ビームのスポットサイズ内のどの位置においても、最大平均パワー密度(Max Average Power Density、「仕様」タブ参照)を超えないことが重要です。
対応するパワーメーターコンソールとインターフェイス

The sections below describe the various designs of Microscope Slide Power Meter Sensor Heads. Use the following links to jump to a specific section:
An illustration to show the behavior of light exiting a high NA objective after it enters the S170C microscope power sensor head vs. a typical photodiode sensor. For objectives with NAs greater than 1.0 and a detector without index matching gel in the gap, some of the light will also undergo total internal reflection at the ND filter-air interface, causing additional losses before the light reaches the sensor. (Important Note: Do not place immersion oil or other immersion media directly on the ND filter of any Thorlabs photodiode detectors other than the S170C and S171C sensors, as they were not designed for this application and the oil cannot be cleaned from the filter surface.)
Large Active Area and Index Matching Gel
The S170C, S171C, and S175C microscope slide sensor heads were designed with large-active-area detectors to accommodate high NA objectives. In addition, the S170C and S171C sensors use index matching gel in the gap between the neutral density filter and the sensor to minimize losses due to internal reflections at the air-glass interface. The S175C sensor uses a protective glass cover that features a smaller air gap than the S170C sensor (0.15 mm versus 1.5 mm) to avoid the use of index matching gel, which helps maintain a fast sensor response time.
The schematic to the right illustrates the advantages that a large-area detector like the one used in the S170C sensor provides over typical photodetectors by tracing the path of light from a high NA objective after it enters an S170C microscope slide sensor head and a typical photodiode sensor. The typical photodiode sensor shown in the drawing has an air-filled gap between the ND filtera and the sensor and a Ø9.5 mm active area, similar to our S130 slim photodiode sensors or S120 standard photodiode sensors. When light from a large NA objective reaches the interface between the ND filter and the glass, it refracts away from the center of the sensor. Some of the light misses the edge of the small active area of the photodiode, causing erroneous power measurements.
In the S170C microscope slide sensor head, the gap between the neutral density filter and the sensor active area has been filled with an index matching gel. Compared to the ND-filter-to-air interface in typical sensor heads, the gel minimizes the amount of reflected light at the ND-filter-to-gel interface that would otherwise not reach the sensor and eliminates refraction of light exiting the ND filter, allowing the large-area detector to capture more light from the objective. Please be aware that this design cannot completely compensate for this effect for very high NA oil objectives and at certain wavelengths.
Similar results would be expected from a comparison of the S175C unit with other thermal sensors. The small 0.15 mm air gap between the protective glass plate and the thermal sensor minimizes the light refracted away from the center of the sensor, while the large 18 mm x 18 mm active area catches more of the incoming signal. Additionally, the S175C sensor has a protective class cover plate that allows the appropriate immersion media for the objective to be applied without damaging the sensor. (Note: do not apply immersion media to Thorlabs' other thermal sensors, as it may damage to the sensor head.)
- Do not place immersion media directly on the ND filter of any Thorlabs' photodiode sensors, with the exception of the Microscope Slide Power Sensors that are specifically designed for this application, as the oil cannot be cleaned from the filter surface. The example used here is only intended to demonstrate the advantages of the S170C sensor's optical design.
Click to EnlargeAn illustration to show the optical design of the NS170C Microscope Slide Peak Power Sensor. An ultrathin β-BBO crystal is used to convert femtosecond NIR laser pulses into their visible second harmonic. Shortpass filters reflect the residual NIR light, allowing only the visible second harmonic light to transmit to the silicon photodiode sensor.
Nonlinear Crystal with Silicon Photodiode Sensor
The NS170C Microscope Slide Peak Power Sensor was designed to measure the relative peak power of two-photon lasers. As shown in the diagram to the right, the sensor features a 30 µm ultrathin β-BBO crystal that converts incident femtosecond NIR pulses (780 – 1300 nm) into their second harmonic (390 – 650 nm). Shortpass filters underneath the β-BBO crystal reject the residual NIR light, allowing only the visible second harmonic light to transmit down to the large area silicon photodiode sensor.
A microscope objective is shown focusing the femtosecond NIR pulses into the β-BBO crystal through a Ø4.5 mm entrance aperture. Because the SHG process requires high peak intensities, the sensor only generates detectable second harmonic light when the ultrathin β-BBO crystal is in the focus of the objective. This means the NS170C sensor is sensitive to the peak power density of the focused femtosecond pulses rather than the average power; therefore, the detected SHG signal can be used as a relative measurement of the lasers' peak intensity. For more details on the generation of second harmonic light using β-BBO crystals, please see the SHG Tutorial tab.
At the top of the NS170C sensor is a standard 170 µm thick cover glass that is sealed to the housing, allowing it to be used with dry, water immersion, and oil immersion objectives. The immersion media can be placed directly on the surface of the cover glass without damaging the sensor. The working distance from the top of the cover glass to the β-BBO crystal is 0.22 mm. Between the cover glass and the β-BBO crystal is an 80 μm air-gap, which is necessary because epoxy or index-matching gel would burn in the focus of the high-intensity femtosecond pulses. While this air-gap causes total internal reflection (TIR) of the highest spatial frequencies when using high NA objectives, the second harmonic process in the β-BBO crystal has a finite spatial frequency acceptance bandwidth, which is exceeded by high NA objectives. Therefore, the highest spatial frequencies rejected by TIR would not appreciably contribute to the SHG process.
The housing of the NS170C sensor shares dimensions with a microscope slide and can fit on standard microscope stages, allowing for measurements of the relative peak power at the focus of a microscope.
For more information on the NS170C sensor, please see the full presentation for our microscope slide peak power sensor for two-photon lasers.

(posted 2024-05-03 12:18:51.34) Newport is offering a photodiode microscope power sensor up to 600mW instead of the 150mW of the S170C.
https://www.newport.com/f/microscope-slide-photodiode-sensor
Sadly we had bad experience with the thermopile version and we would like to a photodiode alternative.
Is it possible to buy a calibrated version with 600mW of the S170C? dpossin
(posted 2024-05-06 09:18:13.0) Dear Peter,
Thank you for your feedback. At the moment I am not sure if we could extend the S170C to 600mW. I reach out to you in order to discuss your application in more detail. Vanessa Carlos
(posted 2023-04-28 15:02:03.27) Hello,
I would like to know if this power sensor can be completely immersed in water. Or if you have any other photodiode sensors where that is possible. I would need it for measuring power at the sample, on light sheet microscopes, using water immersion objectives, with low NA.
Thank you! dpossin
(posted 2023-05-02 04:33:31.0) Dear Vanessa,
Thank you for your feedback. The S170C is desgined for usage in immersion media. You can see the basic working principle here: https://www.thorlabs.de/newgrouppage9.cfm?objectgroup_id=2191&tabname=optical%20design. I am reaching out to you in order to discuss this further. Jolanda van Iperen
(posted 2023-01-09 16:35:59.607) I am looking for a mini laser intensity power meter that fits under the objectives of a u-Raman microscope (till 100x objective WD 0,17 and can focus with that working distance. It should be able to set laser at 532 nm and 785 nm in order to measure at these wavelength the power of the laser through the objectives, preferable reading the power outside the enclosure, which can be opened a little bit. I came to S170C, but cannot find if this is set to a particular wavelength or gives a spectrum. It would be nice to have both options - also for the LED light of the microscope- , but if not in the first place we prefer the first option to measure intensity of laser 532 and 785 nm. hkarpenko
(posted 2023-01-10 08:45:30.0) Dear Jolanda,
thank you for your feedback. Our sensors won´t be able to show the spectrum of the sensor, but only the power. S175C might be a more suitable sensor if you are measuring both, monochromatic and broadband lightsources. I contact you directly to discuss this in more detail with you. user
(posted 2021-11-09 06:01:57.003) What is the typical ambient-stabilization time between you take it in your hand, place it where you want to measure, and until you can actually measure? In our temp controlled lab, I've seen that this can go up to 10-15 minutes. Is that normal? dpossin
(posted 2021-11-16 06:02:54.0) Dear Carlos,
Thank you for your feedback. The stabilization time depends on the power level you would like to measure. In general thermal power sensors are very sensitive to external heat. Since convection is quite a slow process a settle time of 10 to 15 minutes is nothing to worry about. I am reaching out to you to discuss this further. Holger Knaut
(posted 2021-07-29 10:12:16.853) Hi,
is the S170C compatible with laser light illumination such as a confocal or spinning disk scope?
Thanks soswald
(posted 2021-08-02 03:11:26.0) Dear Holger,
thank you for your feedback.
The S170C can be used to measure laser light as long as the maximum power of 150 mW and the maximum power density of 20 W/cm² are not exceeded.
Please contact your local tech support team with more details on your light source, expected power and power density to discuss your application further. user
(posted 2019-07-03 16:32:40.697) We are looking for a power meter similar to this but maybe one that is a cylinder as we are wanting to characterize an assembly that is illuminated from six points located around the circumference.

(posted 2014-01-21 16:09:02.123) I just noticed that my comment is the same as one posted here. We need this device built with a stronger ND filter as we will have powers closer to 1W down on the sample. Seems like a reasonable option to offer a high power version. tschalk
(posted 2014-01-23 04:56:30.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. At the moment we are not able to equip the sensor with a stronger ND-filter because these does not meet our specifications. 1W is far away from the current specification and we hope to increase the maximum power level up to 300mW in the future. I will contact you directly to discuss your application. flickingerd

顕微鏡用のスライド型パワーメータフォトダイオードセンサーヘッドS170Cおよび S171Cは、標準的な正立および倒立顕微鏡のスライドホルダに適合するように設計されており、これらを用いて試料面における光パワーを測定することができます。受光面は密封された筐体に納められており、その前面には光学濃度(OD)1.5 (型番S170C)または0.4 (型番S171C)のNDフィルタが付いています。NDフィルタ上の20 mm x 20 mmのくぼみには、カバースリップや液浸材を入れられます。液浸材(水、グリセロール、油など)はこの中(NDフィルタの上)に直接つけることができます。または、クリーニングを容易にするために、最初にカバースリップを挿入することもできます。S170CとS171CのNDフィルタとセンサの間の隙間には屈折率マッチングジェルが入っており、空気とガラスの境界面での内部反射による損失は最小限に抑えられています。これらの物理的特性については、「光学設計」タブにその概要が記載されています。
このフォトダイオードセンサS170Cは、1 µsの高速応答時間、10 nWの最小検出光パワー、1 nWの分解能といった特性を有し、低パワーの照明の光パワーを高分解能で測定するのに適しています。また当社では、最小検出光パワーが1 nW、分解能が0.5 pWのセンサS171Cもご用意しております。水浸対物レンズを用いるときは、水により特に近赤外域において透過光の一部が吸収されます。そのため、水が無いときの光パワーの読取値は、水が有るときの読取値よりも高くなります。
スライドの背面にはセンサの仕様とビームアライメント用のグリッドが刻印されています。センサを対物レンズに向けるだけでパワーの測定を行うことができます。倒立顕微鏡では、透過照明用ランプをグリッドの中心に置くことで、センサがビームの中心にあることを確認できます。

The NS170C sensor is designed to measure the relative peak power of two-photon lasers by utilizing a second-order nonlinear β-BBO crystal to convert incident ultrafast NIR pulses into their visible second harmonic. Shortpass filters underneath the β-BBO crystal reject the residual NIR light, allowing only the second harmonic light to transmit down to a large area silicon photodiode sensor (see Optical Design tab for details). Because the efficiency of second harmonic generation (SHG) is proportional to the peak power density, or peak intensity, of the NIR femtosecond pulses, the magnitude of the detected second harmonic light provides a relative measurement of the peak power of the laser.
The NS170C sensor can be used with femtosecond lasers with center wavelengths from 780 nm to 1300 nm and average powers from 0.5 mW to 350 mW; however, because the photodiode measures the converted SHG signal, it is not sensitive to the average power of the input laser alone, but rather the peak power density of the laser pulses. The damage threshold for the peak power density is 10 TW/cm2 at 80 MHz repetition rate and for microscope objectives with NA > 0.5; the damage threshold will be lower for NA < 0.5. The photodiode sensor can detect SHG light with wavelengths from 390 nm to 650 nm at optical powers from 10 nW to 5 mW with a resolution of 1 nW. Please see the Specs tab for more information.
The NS170C sensor has the same footprint (76.0 mm x 25.2 mm) as a standard microscope slide and is compatible with microscope slide holders of standard upright and inverted microscopes. This design enables the sensor to measure the relative peak power at the focus of the microscope, making it ideal for laser pulse optimization for multiphoton imaging. The sensor is also post-mountable via an 8-32 (M4 x 0.7) tapped hole, allowing for the relative peak power to be measured in an optical set-up of standard optomechanical components.

As shown in the photo to the left, the housing of the NS170C sensor features a knurled adjustment wheel to tune the angle between the light's polarization orientation and the β-BBO crystal's optical axis. At the entrance of the sensor is a 170 µm thick cover glass sealed to the sensor housing, allowing the sensor to be used with dry, water immersion, and oil immersion objectives. The working distance from the top of the cover glass to the β-BBO crystal is 0.22 mm. The back of the sensor housing features a laser-engraved alignment crosshair that marks the active sensor area to aid in aligning and focusing the beam.
Thorlabs recommends yearly recalibration of the NS170C sensor. Recalibration of a single-channel power and/or energy meter console or interface is included with the recalibration of a sensor at no additional cost. For more information on recalibrating the NS170C sensor, please contact Tech Support.
