I have looked through the user manual for multiple DMD chips and found that the maximum illumination on the DLP9500 is around 11W/cm^2 or 26.6W in the 400-420 nm range, but is only thermally limited in the rest of the visible spectrum. I was also looking at a projector from your digital cinema partner, BARCO, which uses a 1.38" 4K DMD along with up to a 7kW lamp. Assuming a 5% luminous efficiency for the lamp, that results in 350W on the chip, or 69.2W/cm^2. I am assuming this high power density is largely at higher wavelengths than 400-420 nm so the 11W/cm^2 maximum power density isn't a limiting factor and additionally, the chip must have some thermal management system to control the maximum temperature. I have a few questions: can your smaller chips also come with some kind of cooling system to operate at similar power densities and if so do you know of an estimated maximum flux these chips can handle with appropriate cooling? (If this is a better question for DLi or another partner, let me know). Also, I am hoping to operate at near-UV wavelengths, is 11W/cm^2 really the maximum flux at those wavelengths or can that value also be raised with appropriate cooling?
Thanks,
