(posted 2023-08-07 15:46:21.38) Good day - I recently purchased a LIUCWHA and a LIU525B.
My question relates to the LIUCWHA.
I am using a CCS100 (recently purchased as well) in conjunction with the LIUCWHA. The wavelength vs amplitude plot of the published data doesn't match what I observe on the CCS100. If I normalise the 465nm trace to have an amplitude of "1" (full scale on the CCs100) then the 2nd peak at about 550nm has an amplitude of about 0.42. I was expecting this 2nd peak to about 0.6, as per data sheet. The CCS100 is being used with its supplied fiber optic cable and no other items connected, and in the "amplitude correction mode". If I repeat the exercise but normalise to half max amplitude "0.5", the situation remains the same, the 2nd peak is at about 0.2.
So also what I am also asking, do all the lamps have an output amplitude spectrum curve close to the published curves, or is it only the total light output that is constant (eg. 3mW/m2).
Thanks hchow
(posted 2023-08-09 10:14:39.0) Dear Mr. Moyes, thank you for your feedback. I will personally reach out to you to provide the necessary information. Thank you. Nicolas Alegría
(posted 2023-03-17 17:42:53.117) Hi, I use the white light LED and I'm trying to collimate it but I'm having trouble with this. Do you recommend any optical element designed for this product or something like that? hkarpenko
(posted 2023-03-20 08:31:50.0) Dear customer,
thank you for your feedback. We usually recommend using aspheric condensor lenses to collimate LEDs, but in case of LED arrays, it might work less efficient. I will contact you directly to discuss this further with you. Anna Alexander
(posted 2021-05-25 18:49:30.78) Is there any way to purchase this product without the plastic diffuser on the front? I would like a quote for this is it's an option. soswald
(posted 2021-05-28 07:11:07.0) Dear Anna,
thank you for your feedback. I have contacted you directly to further discuss your application and explore the possibility of offering a suitable custom solution. user
(posted 2015-10-09 12:54:41.613) Purchased LIU525A and within 20 hours, some of the LEDs were out. We were able to return the unit and get a replacement (with some hesitation from thorlabs). The second unit eventually lost some LEDs, too! For a $200+ unit, I would expect it to last much longer. Therefore, we won't be purchasing any more array lights. jvigroux
(posted 2015-10-12 11:28:50.0) A response from Julien at Thorlabs: We are very sorry about the difficulty you have experienced with this product. The repeated issues you have been having are extremely unlikely. The return and failure rates for the LUI line is very low. We will contact you directly to further discuss the exact environmental parameters in your set up to see if maybe a root cause for the failures can be found there and work out a specific solution. user
(posted 2014-01-08 16:01:16.433) Is it possible to operate 4 LIU104 light sources all at the same time using the DC4100 LED controller and breakout box? tschalk
(posted 2014-01-09 03:57:37.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. The Arrays are equipped with an integrated circuit which drive the individual LEDs and an additional 24V power supply for the whole array is needed. It is not possible to drive the LED Array with our LED drivers and control, for example, the brightness of the LEDs. Please contact me at europe@thorlabs.com if you need any further information. prdm2
(posted 2013-09-11 11:54:39.253) Hello, I was hoping you could suggest which type of safety glasses filter material would be suitable with use for these products?
Thankyou jlow
(posted 2013-09-11 09:03:00.0) Response from Jeremy at Thorlabs: We will contact you regarding this. You can contact a local office to discuss about your applications in the future. Our contact information is provided at http://www.thorlabs.com/locations.cfm. nicolas.beaugerard
(posted 2013-06-28 12:14:51.117) Hello, I would like to know how to control the LED brightness.
I guess that I need to add a potentiometer between the pin 2 and the ground. Is that's corect? More over, what resistivity do you recommend ? tschalk
(posted 2013-07-03 08:06:00.0) This is a response from Thomas at Thorlabs. Thank you very much for your inquiry. A typical control unit is shown in the manual of the LED Array: http://www.thorlabs.de/Thorcat/16000/LIU004-Manual.pdf. The LED brightness can be controlled by a variable controlled current device. The maximum current for the LED Array is 120mA. I will contact you directly for more detailed information. jvigroux
(posted 2012-10-11 12:43:00.0) A response from Julien at Thorlabs: Thank you for question! There is no need to add an extra resistor. The LIU are designed to work with 24V input voltage and as such there is already a input resistor to ensure that the current through the LED is correct for this voltage user
(posted 2012-10-11 06:59:35.487) I need to clarify the example circuit in the manual.
Do we need to add a load resistor in series with a 24V PSU to fix the current to max intensity or does the LIU004 have this already. we do not want to connect a pSU directly to this if it unprotected. jvigroux
(posted 2012-07-11 07:28:00.0) a response from Julien at Thorlabs: thank you for your inquiry. The weight of the LIU004 is about 96 grams. joseph.hampton
(posted 2012-07-10 13:13:04.0) Hello,
do you know the approximate mass of LIU004?
cheers! jvigroux
(posted 2012-06-20 08:21:00.0) A response from Julien at Thorlabs: Thank you for your feedback! In principle, the LED should indeed work with no optical power reduction for the specified time. The specified time is however valid only for the conditions it was tested in (temperature, voltage, voltage and current stability...). I will contact you to discuss the way the LED was used and see if there is maybe an external factor that could have precipitated the degradation of the LED. If not, we would of course exchange the LED within the warranty. david.lee
(posted 2012-06-18 10:10:23.0) The stated operating lifetime for the LIU004 LED light source is up to 100,000 hours which is approximately 11 years. We have two of these units, both operating with the LIU-PS power supply. On one unit 10 of the LEDs have failed. On the second unit many of the LEDs now have significantly lower brightness than the brightest LED causing the source appear highly non-uniform. I suspect the dim LEDs will fail soon. Both units have only been operated for approximately 1,000 hours. Is LED lifetime a known issue? Could we improve the LED lifetime by operating at a lower power? Any comments regarding improving the lifetime would be appreciated. jvigroux
(posted 2011-12-08 10:20:00.0) A response from Julien at Thorlabs: Unfortunately the compliance voltage of the LEDD1B is around 12V while the required forward voltage for the LIU001 is 24V. The LEDD1B is meant to be use primarily with our high power mounted LEDs. The most suited adjustable LED driver for the LIU00X would be the DC2100 due to its high compliance voltage. jripoll
(posted 2011-12-07 08:22:51.0) Dear Sirs,
Can the LIU001 be used with the LEDD1B to regulate its intensity?
Thanks and best regards,
Jorge klee
(posted 2009-10-19 10:41:29.0) A response from Ken at Thorlabs to mhyde5: Unfortunately, we are unable to offer an LED light source at 1550nm at this time. mhyde5
(posted 2009-10-16 10:39:32.0) I see in the comments below that you were able to construct an LED light source at 780 nm. I was wondering if you could construct one at 1550 nm? I have 5 of your unmounted 1550 nm LEDs; however, they do not provide enough light for my application.
