DLPD4X00KIT: Laser Light Source Projector Design

Part Number: DLPD4X00KIT
Other Parts Discussed in Thread: DLP650LNIR

Hello.


I would like to design a laser light source projector to create a structured lighting system.
(1) Is there an optical system that is an example of a laser light source?
(2) Is there a difference between telecentric and non-telecentric depending on the presence or absence of a prism in the optical system of the DLP™ system, and does it affect the laser source, such as interference from DN2509927?
If it is a simple design, there is no need to put in a prism.
(3) If a prism is needed, I would like to know if there is a prism that fits the DLP650LNIR.

Thank you for your help.

    Hello User,

    Please contact ViALUX (Europe) or Digital Light Innovations (US).  They do have some optics, but you would have couple in your laser.  Please see the following page as a starting point.  Check with them about whether there is a prism in the design.

    The prism simply makes the design more compact.  We will have to ask one of our optical experts regarding the telecentric vs. non-telecentric.  

    Regarding the Application Note you reference, there will always be some diffraction effects when using laser.  Making the aperture larger will help some.
