Hi,
We are planning on using a DMD to shape and phase modulate a laser beam to trap atoms. The laser we are using is 1090 nm and can go up to 10W.
1) Can I see a transmission curve for the window of the LCr 4500? Is it the same as that of the Light Commander?

Are there coatings available? the NIR version is not worth the expense for out application.
2) can I see specs for the maximum power intensity for the DMD. I have reviewed the available documentation and can not find this particular information. I expect based on conversations with one orf the development houses that 10w might be a lot but not too much as long as it is not concentrated onto a small region.
3) I see from other posts that the DMD window is accessible by laser once the light engine has been removed (which I assuming is a fairly straightforward process, any information on that is also appreciated). Exactly how accessible is it; what i mean is the DMD mounted on the side light the Lightcrafter 3000 or is it tucked underneath? Are there flex cables that allow more precise positioning?
4) A side question, are there any capabilities that the Lightcrafter 3000 has beyond those of the 4500? I'm aware of some differences like the number of images is limited to 48 1 bit depth as opposed to 96, but is the basic functionality all there?
