DLP9000XUV: Model for direct writing applications

Justas Baltrukonis

Part Number: DLP9000XUV
Other Parts Discussed in Thread: DLP9000

Dear all, I`m currently working on a zemax model for using DLP9000 for direct writing application. By any chance someone could share a Zemax example on how to implement a dmd model correctly? not necessarily same dmd or same application, It would same me a lot of time. I`m currently using zemax` us_mems.dll model for this

thanks

Justas,

Let me get some advice from the optics team and get back with you today or tomorrow.

Hello again Justas,

Here is what the optical team provided:

The us_mems.dll is the surface we use to model the DMD in Zemax. An optical reference design including the DMD surface can be found here:

https://www.ti.com/tool/DLP5530PGUQ1EVM

Look for the design files download link on that page.

The important parameters when setting up the us_mems.dll surface are:

X-width & Y-width to match DMD active array dimensions
Angle 0 to change pixel tilt angle
Rot Angle to adjust pixel tilt direction
# X pixels and # Y pixels can be set to small values, they do not need to match the true DMD pixel count

I hope this helps.
