Other Parts Discussed in Thread: DLP9500UV
We are now purchasing DMD products that can be used in the 355nm plused laser.
The products DLP9000XUV and DLP9500UV can be used in the band of<400nm, but the maximum illumination power density at 355nm varies greatly (2.5W/cm2 and 2mW/cm2 respectively).
As far as we know, the damage threshold of mirrors with aluminum coating is relatively high. For example, the damage threshold of Thorlabs' mirror (PF10-03-F01) is 0.3 J/cm2 at 355 nm (pulsed laser, 10 ns, 10 Hz) and 100 W/cm at 355 nm (CW Laser). We have a few questions that we hope to get your professional answers.
(1) Is the coating of micro-reflectors in DLP9000XUV and DLP9500UV the same, and the coating of protective glass the same?
(2) What is the reason why the maximum illumination power density of DLP9000XUV and DLP9500UV are so different?
(3) The maximum illumination power density given in the product technical description is under CW laser. Can you give the damage threshold under pulse laser according to the coating process of micro-mirror and protective glass, or give a reliable and safe conversion method, maybe you can refer to the Thorlabs website（ https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=12393 ）
It is very important for us to know the damage threshold of each product under pulsed laser. We look forward to your reply.
