Dear all,
I'm currently prototyping a system based on the DLP5500, which for now comes from a Hg-HID lamp-based projector which I "hacked". The ref number of the DLP extracted from the projector is 1076-6439B. Analyzing the reflectance (with a spectrometer) of this DMD+protective window, I observe a severe drop of reflectance in blue area, which makes sense since the lamp produces a lot of blue light compared to the rest, and a projector is supposed to send an almost spectrally flat spectrum.
The problem is that this reflectance does not correspond to that of the Corning Eagle XG glass described in the DLP5500 datasheet. For some reason I need quite some flux in the blue area of the spectrum, and I'm therefore wondering if, apart for the protective window coating, I should expect any change on the electronic side between the genuine DLP5500 and the 1076-6439B? If not, then I could make a simple replacement of the 1076-6439B with the genuine DLP5500.
Thanks for your help,
Simon
