ファイバ出力型LEDの特長
- 公称波長範囲:280~1450 nm
- 温白色(4000 K)、冷白色(6200 K)、広帯域(470~850 nm) LEDもご用意
- 内蔵のEEPROMがLED動作パラメータを記憶
- 最適化された温度特性により安定した出力を実現
- マルチモードファイバーパッチケーブルの接続に適したSMAコネクタ
ファイバ出力型LEDは、バットジョイントと呼ばれる接続技術を使ってファイバに結合させた高出力シングルLEDを利用します。 このプロセスによりファイバ端がエミッタにできるだけ近づくようファイバーコネクタを配置しているので、ファイバ入力部での光損失が最小限に抑えられ、出力パワーが増大します。結合効率は、主として接続されているファイバのコア径とNAによって決まります。 より大きなコア径とより高いNA値によって、ファイバ端面における光損失は減少し、出力パワーは増大します。また、400 nmよりも短波長のLEDには高OHファイバのご使用をお勧めしています(推奨パッチケーブルについては下表をご参照ください)。
なお、これらのファイバ出力型LEDのコネクタに接続できるのはSMAコネクタだけですのでご注意ください。LEDへの機械的損傷を防ぐため、取り付けるコネクタのフェルールの長さは、規格EN61754-22:2005で規定されているSMAコネクタでの最大許容長さ9.812mmを超えないようにしてください。
各LEDのスペクトルや関連データのファイルは右表内のリンクをクリックするとご覧いただけます。LED同士を比較していただけるように、複数のウィンドウを同時に開くことが可能です。
最適化された温度管理
高出力のファイバ出力型LEDは、優れた熱安定特性を持っています。 LEDがマウントされた金属コアの回路ボードに、長さ34 mmのパッシブ冷却ヒートシンクが直接接触しています。これにより、LEDの接合温度の上昇による光出力の低下を最小限に抑えることができます。当社の高出力ファイバ出力型LEDの一部製品(M365FP1、M385FP1、M395FP1、M405FP1、M660FP1)は、放熱と温度安定特性を高めるため50 mm長いヒートシンクにマウントされています。
白色LEDと広帯域LED
当社の冷白色および温白色LEDは数百nmにわたる広帯域スペクトルを有しています。これら2つのLEDの色の違いは相関色温度(色が最も近い黒体放射の温度)を用いて表わすことができます。一般的に温白色LEDはタングステン光源に近いスペクトル、冷白色LEDは、それよりも青色成分が強いスペクトルを有しています。冷白色LEDは温白色LEDに比べてほとんどの波長において発光強度が高いため、蛍光顕微鏡の用途やカメラのホワイトバランスに適しています。
ファイバ出力型LED MBB1F1は、広い波長域において比較的平坦なスペクトルを得られる設計となっております。 FWHM幅は500 nm~780 nmで、10 dB帯域幅の範囲は470 nm~850 nmとなっております。この広帯域光源のスペクトルについては右の表をご覧ください。
ドライバ
当社では、LEDに対応するドライバとしてLEDD1B、UPLED、DC40、DC2200、DC4100、DC4104の6種類をご用意しています(DC4100とDC4104にはDC4100-HUBが必要です)。ドライバの仕様については「LEDドライバ」タブ、対応するするドライバについては「仕様」タブをご覧ください。ドライバUPLED、DC40、DC2200、DC4100、DC4104は接続されたLEDのEEPROMから電流のリミット値を読み取り、最大電流値を自動的に設定してLEDを保護することができます。
光刺激用オプトジェネティクス実験用途
当社のファイバ出力型LEDは、オプトジェネティクス用途にも適しています。幅広い波長のラインナップと機構部の相互接続性が特長の製品となっております。また当社のLEDドライバDC4100ならびにコネクターハブDC4100-HUBを使用すると最大4つの光源を同時に駆動ならびに変調することが可能です。こちらをクリックして当社のオプトジェネティクス製品のラインナップをご覧ください。
パッチケーブルの選択
こちらのLEDは当社の多くのマルチモードファイバーパッチケーブルが取り付け可能です。LEDの出力波長に応じたファイバーパッチケーブルについては下表をご覧ください。SMAコネクタ付きパッチケーブルに加え、当社では片端にSMAコネクタ、もう一方の端にFC/PCコネクタ、フェルールあるいはファイバ素線がついたハイブリッドパッチケーブルもご用意しております。標準品としてご提供していない構成については当社のカスタムパッチケーブルのページをご覧ください。

LEDの寿命および長期的なパワー安定性
LEDの特性の1つとして、時間の経過と共にパワーが自然に低下することがあげられます。 ほとんどの場合、パワーは緩やかに低下しますが、急速な低下や完全な停止、あるいは故障が突然起こることもあります。 LEDの寿命は、LEDの種類ごとに規定されたある割合のLEDが、あるパワーレベル以下に低下するまでの時間で定義されます。 寿命測定のパラメータはBXX/LYYで表され、ここでXXはその種類のLEDで寿命が過ぎた後の出力パワーが規定値のYY%以下になるLEDの割合を示します。 当社では、LEDの寿命をB50/L50で表しますが、これはその型番のLEDのうち50%のLEDの光パワーが規定の寿命がきた時に初期値の50%以下に低下するという意味です。 例えば、定格出力パワー150 mWのLED100個のうち、50個の出力パワーが規定の寿命を過ぎたときに75 mW以下に低下するということです。
最適化された温度管理
こちらのファイバ出力型LEDの放熱は安定な出力のために最適化されています。 ヒートシンクはLEDマウントに直接取付けられていて、熱的接触は適切な状態になっています。 これにより、LED接合面の温度の上昇によって生じる光出力パワーの減衰を最小に抑えることができます。

LEDの駆動電流によるスペクトル変動
すべてのLEDは駆動電流の変化によりスペクトルプロファイルならびにピーク波長が変化します。当社のファイバ出力型LEDについては光スペクトラムアナライザ(OSA)を使用し、駆動電流がゼロに近い値から最大値まで増加したときの波長シフトを調査しました。
LEDの発光プロファイルは比較的広がりがあり非対称です。LEDの重心波長は、発光プロファイルにおける波長の加重平均です(質量中心の計算と似ています)。次の式で与えられます。
ここに、I(λ)は波長λ毎での強度です。よってここでは電流の変化に対するLEDの重心波長を追うことにより、ピーク波長のシフトとスペクトルプロファイル全体の変化の影響を捉えます。 OSAのPeak Trackモードでは、ユーザ設定の強度の下限値を使用して計算に必要な波長の上限ならびに下限(λ2とλ1)を求めることにより、スペクトルピークの重心波長を自動的に計算します。ここでは強度の下限値をピーク強度より6 dB下がった値に設定しました。
各LEDには高出力LEDドライバDC2200を使用し、プリセットした電流値でLEDを駆動しています。各電流値ではOSAでLEDスペクトルを5回走査し、これらを合わせて平均スペクトルを生成しました。OSAは予測されるピーク波長の50 nmの範囲内で最大の強度値を探すことでピーク波長を特定し、上記に説明した方法で重心波長を計算します。重心波長はLEDの電流リミット値まで0.05 A毎に求められました。全てのプロセスはLED毎に4回繰り返し行いました。 OSAによる計測はすべて絶対パワーならびに高分解能分光モードで実施されています(OSAの動作モードについては製品紹介ページをご覧ください)。
計測結果は下表に掲載しています。グラフのアイコンをクリックしてご覧いただけます。各LEDの重心波長は、それぞれの電流値で得られたすべての値の平均値を求め、プロットされています。すべての実験における各電流値での最小ならびに最大波長が測定され、赤いエラーバーで示されています。最小電流値ではLEDの強度が弱すぎてノイズレベルを超えず、波長を正確に測定することができませんでした。そのような影響を及ぼす電流値はグラフから省かれています。
実験の制約
- 型番毎に1つのユニットのみをテストしました。プロット図は電流毎の重心波長の一般的な変化を示すもので、出力波長の絶対値ではありません。同じ型番でもLEDにより重心波長にばらつきがでる可能性があります。
- LEDは温度制御されていません。

 (posted 2024-03-20 13:28:33.177) Hi, i have a M590F3 source. I am interested of the shift wavelength for this source. I hav read the graphic for M595F2 beacause this source is near in term of wavelenght. It seems there is a mistake with the graphic because the waveleght value do not correspond to the M595F2 source. hchow

I recently purchased
MCWHF2, 6200K, Cold white LED from thorlabs. I only used it couple of times and the LED seems to not working now. I did pay attention to the current and was kept within the requirement mentioned in the data sheet.
I also did try to check inside this LED and I think that the metal core LED is damaged and needs to be replaced. Could you please provide some assistance as how to achieve this? Is it possible to purchase single metal core PCB LED compatible with this
MCWHF2 light source from you and replace it by ourselves?
Or do we need to ship it back to you for replacing it. The device was purchased in July 2023 for your reference.

 (posted 2022-03-01 12:14:57.417) Hello Thorlabs,
the specs datasheets of the fiber coupled LEDs state: "Optical power increases proportionally with the core diameter and nearly proportionally to the square of the NA."
Why is that so instead of being proportional to the core area (thus diameter squared)?
Best regards
Dirk wskopalik
 (posted 2022-03-16 09:20:03.0) Thank you very much for your feedback!
It depends on the dimensions of the LED emitter compared to the fiber core if the power increases proportional with the core diameter or proportional with the square of the core diameter, i.e. the core area. For these fiber-coupled LEDs, the emitter is in most cases larger than the used fibers so the power is usually proportional with the core area. We will check and correct the statement in the spec sheets.
Please note however that this proportionality should only be considered a rule of thumb. There may be deviations from this proportionality between different fibers due to the fiber type, OH content in the fiber, NA of the fiber, etc.
I have also contacted you directly to discuss this in more detail. M. H.

Thanks dpossin
 (posted 2022-02-21 05:21:51.0) Dear customer,
Thank you for your feedback. We generally do not recommend to increase the current over the specified maximum as this can lead to reduced lifetime or damage. However the optical output power can be increased by using a fiber with a larger core diameter. For example the output from M780F1 has been increased by a factor of around 5 by using a 1000µm core fiber (M30L02). I am reaching out to you in order to discuss this in more detail. user

Or would it be possible to use a multi-mode fiber with a core diameter > 400 µm to increase the power further? Thanks in advance and best regards. MKiess
 (posted 2020-12-15 10:39:43.0) Thank you very much for your inquiry.
If you use a fiber with a larger core diameter and a larger NA, this will lead to higher optical output powers at the fiber output. We recommend using multimode (MMF) fiber with the MWWHF2. Optical output power is specified for a Ø400 μm MMF with an NA of 0.39 at the maximum allowed LED current. Optical power increases proportionally with the core diameter and nearly proportionally to the square of the NA.
I have contacted you directly to discuss further details. Naveen Tangri
 (posted 2020-10-23 16:05:09.817) Hello,
We're located in Santa Clara, California and we're looking for OEM quantities of broadband unmounted SMT LEDs for embedded applications. We looked at your LEDSW50 but its spectral power distribution curve is too "wavy gravy". However, the LED used in your MBB1F1 appears to have a flatter and more uniform spectral curve.
So here's the question...would Thorlabs be willing to sell just the LED used in your MBB1F1? We'd be open to signing some sort of "non-compete" agreement, if required.
Sorry for the oddball question, and "no" would be a perfectly acceptable response, but we wanted to know either way.
Thanks and best regards! MKiess
 (posted 2020-10-27 07:01:49.0) Dear Naveen, thank you very much for your inquiry. The right LED for your application in this case is probably the MBB1D1. This broadband LED ranging from 470nm to 850nm and has a relatively flat spectral emission over this wavelength range. Furthermore, this is the pure LED on a metal core PCB.

 (posted 2017-10-19 10:03:13.0) This is a response from Wolfgang at Thorlabs. Thank you very much for your inquiry.
The driver LEDD1B is specified with a current ripple of 8mA. This ripple could also be seen in the light emission of the LED. The M780F2 has a max current of 800mA so this would correspond to 1% variation.
The LED itself will show a decrease in power during operation which would depend e.g. on the current and on the ambient temperature. This decrease is typically in the range of 3-5%. When the LED is switched on, there might also be some short term overshoots due to the driver or due to temperature changes. Other variations are not expected.
I will contact you directly to talk about your requirements in more detail. fmor82

The thing which I don't understand is that the coupled light is the same that with the other of 0.39NA. It is supposed that it would be less the coupled light with 0.22NA than 0.39NA, but you haven't change any value, so I'm a bit confused. I thought that with 0.22NA the coupled light will be 3.14 times less than with 0.39NA.

Today, I come back from holidays, and I see that some changes have taken place, you have change the fiber characteristics for fiber coupled light power.
Last month, they were a fiber of 400 um and 0.39 NA and other of 200 um and 0.39 NA, but today the 200 um fiber has 0.22NA.
I'm surprised that the light coupled power values doen't change in any case because I thought that it depends of fiber characteristics.
Since I know, the coupled light must be 3 times less in 0.22NA case compared with 0.39NA case.

 (posted 2015-03-19 16:51:17.157) Hi, I was looking the M420F2 coupled light source to purchase it, because his great coupled power, 8.9 mW in 200um fiber. But then I read the datasheet, and I look that there puts that the minimun power coupled in a 400um fiber is also 8.9 mW... It is also strange that in others light sources usully the power coupled in 400un core fiber is 4 times bigger than in 200um(for example M365F1 200um:1mW and 400um:4.1 mW), but in 420nm case is less than 2(200um:8.9mW and 400um:16.2 mW).
So the question is, is really that the power coupled in 200um fiber is 8.9 mW??or is another value?? shallwig
 (posted 2015-03-20 06:54:48.0) This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The specifications as stated on the website for these LEDs were measured and are correct so far. The assumption by increasing the core diameter and NA to increase the power proportionally does not take into account that each LED type has a different size and viewing angle (directional characteristic) which also influence the coupling efficiency.
All the numbers we provide on the web and in the datasheets are based on real measurements. We always treat the measurements quite conservative which means that we reduce the results typically by 10%. We measure up to 5 different LEDs with 5 different patch cords. Then we take the average and the minimum value and reduce it by 10% for our specs. By accident for this specific LED the minimum power with a 400µm fiber is nearly the same as the typical output power with a 200µm fiber.
The typical output power you can expect with a 200µm fiber is indeed 8.91mW. I will contact you directly to check if you need any further information. andisetiono

 (posted 2012-06-06 11:13:00.0) A response from Julien at Thorlabs: Thank you for your inquiry! There will always be a trade-off to be found between fiber diameter and/or NA (ie. beam quality) and optical power coupled into the fiber. When using a fiber having a NA of 0.39, the focal length for the collimation lens to be used should be about 1mm. The beam quality that would however result from the combined effect of such a short focal length and the fiber diameter would lead to quite high divergence. In you case, I would recommend using a somewhat longer focal length for the collimation lens and subsequently a beam expander for the beam diameter reduction. I will contact you to discuss further the exact requirements of your setup to find what the most suited solution would be. igkiou
