(posted 2024-08-01 14:37:45.323) Can FGL570 be mounted in LMR1/M of your product? jdelia
(posted 2024-08-01 11:15:41.0) Thank you for contacting Thorlabs. Yes, you can mount the FGL750 in the LMR1/M and hold it in place using the SM1RR retaining ring that is included with the lens mount. Manuel Lebrón
(posted 2024-03-14 11:43:23.777) We've bought some of these filters at past. Would like to know the refractive index of it. jdelia
(posted 2024-03-14 01:12:47.0) Thank you for your inquiry regarding the FGL830 filter. This filter is made of Schott RG830 glass. This substrate at a 3 mm thickness has a refractive index of 1.560 at 587.6 nm, 1.550 at 852.1 nm, and 1.550 at 1.014 um. Elyn Xie
(posted 2024-01-12 13:36:35.997) Would it be possible to get the FGL455 or FGL435 in a 3-4mm thick 18mm diameter. Thank you jdelia
(posted 2024-01-17 08:51:55.0) Thank you for contacting Thorlabs. I have reached out to you directly to discuss the feasibility of this customized item request. billmylife90
(posted 2019-02-13 20:43:26.577) Is it pass all the IR wavelength band?
Wanna know about the total band from 800 nm ~ 5000 nm ... YLohia
(posted 2019-02-14 11:53:38.0) Hello, thank you for contacting Thorlabs. The transmission of light > 2700nm falls below 50%. I will reach out to you directly with this data. yoav
(posted 2018-02-07 13:54:17.49) Hello. How many you have in-stock? Thanks tfrisch
(posted 2018-02-09 03:49:08.0) Hello, thank you for contacting Thorlabs. I will have a Sales Representative reach out to you with information on the availability of these filters. If you are looking for higher quantities, we should be able to accommodate those needs as well. jasterb
(posted 2017-07-05 12:32:23.21) Would it be possible to get the FGL570 in a 3mm thick 10mm diameter form or alternatively in a 3mm thick 6 inch square? nbayconich
(posted 2017-07-11 11:12:38.0) Thank you for contacting Thorlabs. I will contact you directly about our custom capabilities. mbraithwaite
(posted 2017-02-21 15:50:40.613) I've tested and proofed the FGL9 filter for my application. In the short term can you quote me qty=10 FGL9 filters edged down to 0.375" diameter?
It's possible that I could need qty=1000 FGL9 filters with 0.375" diameter in 4Q17 and higher volumes later. I should know more about longer tern demand by June.
Thanks Michael Braithwaite tfrisch

(posted 2016-02-19 12:58:02.013) Hi, I'm Hsu from Taiwan. What's the operating temperature of FGL400S? besembeson
(posted 2016-03-03 05:29:22.0) Response from Bweh at Thorlabs USA: You could typically use this in the -50 to 80 deg C temperature environments. jlow
(posted 2013-01-21 16:15:00.0) Response from Jeremy at Thorlabs: The long pass and bandpass filters can be used with Xenon lamp. The specs might differ slightly since the angle of incidence is not 0°. l.costantini
(posted 2013-01-11 16:23:22.247) Hi,
I'm Luca Costantini from Strategie s.r.l. and i should to know if the filter long pass and bandpass operates with xenon lamp tholste
(posted 2012-07-27 17:49:00.0) A response from Tor at Thorlabs to nateb: Thank you very much for contacting us. We also observe fluorescence at 532 nm for this filter - we will update this page with respect to these findings. In the meantime, I will be contacting you to discuss your application. nateb
(posted 2012-07-23 11:30:48.0) Using information from the Schott website and the information contained on the Thorlabs website I chose the FGL590 longpass filter. Unfortunately, I found that the filter fluoresced strongly under 532 nm light.
Using a 15-50 mW 532 DPSS laser I illuminated the backside of the filter and found that there is a visible orange glow emitting from the filter. I would expect an OD5 blocking at this wavelength (532 nm). This fluorescence effect should be listed. tcohen
(posted 2012-07-17 13:49:00.0) Response from Tim at Thorlabs: Thank you for contacting us! I will email you the spectral data. mzlin
(posted 2012-07-16 19:36:05.0) How do these compare to your edgepass filters in slope steepness? I had a difficult time figuring this out with only the graphs showing divisions 100 or 200 nm apart. Would it be possible to email me the spectra of the 715 and 721 longpass colored filters please? Thank you! tcohen
(posted 2012-06-28 14:44:00.0) Response from Tim at Thorlabs: Thank you for your feedback! We have introduced the new FGL570 filters with 25mm OD because of the popularity of the size. We also have a larger version of the CFH1, the CFH2, for 1” diameter filters. If you are interested in ½” filters to retrofit into your system, we should be able to quote this as a custom for you and I have contacted you to discuss this option. cbrideau
(posted 2012-06-27 18:52:41.0) Any chance of getting these in 1/2" round instead of 1"? I'm using the little 1/2" filter holders (CFH1) and I'd like to use these colored glass filters with them. technicalmarketing
(posted 2008-02-14 17:25:57.0) We have double checked and the graphs shown in V19 are incorrect. Please refer to the web for the most up-to-date graphs ghegenbart
(posted 2007-11-20 04:38:25.0) The graph for the BG40 glass in the "Graph" tab is different from the graph shown on the pdf copy of the catalog page in the "Drawings&Documents" tab. |
