Hello,
I am using a collimated laser source to illuminate the DMD chip. I am then using a microlens array to focus the projected light. The projected light needs to be collimated and perpecdicularly incident on the microlenses for the array to focus well. The light coming off of the DMD chip is diffracted. I thought I would be able to use the (0,0) diffracted order, but there is not enough power there. Is there an optical element/system (refractive or reflective) you know of which will collect the higher diffracted orders for my application?
Is the diffraction inevitable? Can it be avoided?
Thank you,
Anthony
