Other Parts Discussed in Thread: DLPLCRC900EVM, , DLPLCR65NEVM
Dear Team,
I am trying to use DMD (DLPLCR65EVM with DLPLCRC900EVM controller) with 940 nm pulsed laser (100Hz, 6ns, about 10mJ/cm2 on DMD surface). Based on the DMD power threshold document (DLPA027), I assume it is safe to use this power. However, when I use a 2mJ/cm2 power of 940 nm laser, the DMD surface seems to be damaged (only observable in the off state). So here are my questions:
1. Based on the description, does this mean permanent damage to the micromirrors?
2. If I switch to a NIR version DMD with higher damage threshold, e.g., dlplcr65nevm, will it solve the problem?
