DLP470NE: DLP general devicess

Part Number: DLP470NE

Dear support,

We would like to use any of DLP product in one special evaluation application. Idea is to use semiconductor laser diode of certain radiometric power and then redirect laser beam to the target.

Target is moving quite fast (like fly) so we need appropriate mechanical system for laser beam change. My question is dedicated to radiometric pressure of light to single mirror or to square mm of mirror area?

How is better to define, to mirror or to  square mm of single chip device? Are there significant differences between product's or we can apply origin data to any of your DLP devicess?

Can you estimate this radiometric power to surface/mirror and also please inform me if there is any difference between wavelength of laser light to mirrors from korpuskular ball model of light? We need to know maximum radiometric power of laser that will not damage the mirrors or that will not change the angle od mirrors.

Also if you can suggest most appropriate device (application is also really price sensitive).

Many thanks for your precious support and wish you nice day,


  • Hello,
    Thanks for using the TI e2e forums! I will look into this and see if I can find some useful information for you.

  • Hello Blaž,

    Danny has asked me to help with this inquiry.

    There are a number of factors that have to be considered. Are we talking about high peak power pulses with very short duration or are we talking about continuous beam of photons. In any case, depending on the time average power density, you may need to provide a cooling solution.

    Even if the average power is low, but the pulse duration is very short and peak power is very high, it is possible to ablate layers of the micromirror with each shot.

    Please provide some information about your proposed use model. The data sheets do provide wavelength ranges and limitations. Providing at least a wavelength operational range will help.
