Hello,
I have a 365nm LED with 9nm of Bandwidth (FWHM), that I need to couple with this DMD device. However, the technical sheet suggests that when this micromirror device is coupled with incoherent light, a filter which nearly extinguishes all wavelengths below 363 nm must be used in the illumination path to the DMD. I am struggling in finding a suitable solution.
Can you advise me on how I could solve my problem? What kind of filter would you suggest?
My nominal LED intensity is 1400mW at 365nm. Would it be fine to use a filter that will allow me to have radiation below 363nm with a maximum intensity below 300mW?
Thank you for your support,
Valeria
