DLP6500FYE: Changing Tilt Angle

Part Number: DLP6500FYE

Hello,

I am using a DLP with a green laser and related optics. My goal is to optically filter the first order reflected from the DLP to illuminate one sample.

As you can see from the attached picture, I have the following situation: on the right the DLP is off and you can see at a certain position the reflected spot. On the left side, the DLP is on and now you can see, of course, two spots that are decoupled of a certain angle. The issue that I am facing is that I need to work with the spot called in the picture "Primo Ordine", which has an output angle that points upwards, while I'd rather like working always on the same plane for different reasons. Thus, my question: is there any way to change this output angle? I'm currently using the DLP GUI 4.0.1 and I did not find any way to control that parameter; I am wondering if there is another software from which I could insert, for instance, a phase map to the DLP in order to have the desired output and tilt angle.

I hope I was clear. Thank you in advance for your understanding.

Best regards,

Matteo

 

  • Matteo,

    The tilt angle is set by the design and construction of the DMD.  There are mechanical spring tips that the mirror lands on which control the tilt angle.  There are only 2 operational states... "on" (12 degrees towards the illumination corner) and "off" (12 degrees away from the illumination corner).  Other than the "on" and "off" states (+/- 12 degrees), the tilt angle cannot be controlled electronically.  

    Hopefully that answers your question.  If you have any other questions, please let us know.

    Auguri per un felice 2021!

    Regards,

    Gary
