DLP2000: Controling the DLP200 for laser modulation without the EVM

Part Number: DLP2000
Other Parts Discussed in Thread: DLP3010EVM-LC, DLPLCR4500EVM

Hi everyone, 

I'm a doctoral student specializing in light modulation systems. My objective is to modulate the laser at 640 nm during my experiments using the DLP2000 chip.

I'm interested in exploring the most cost-effective approach for achieving this. Could you please advise me on the necessary components?

Is it necessary to purchase the EVM as well?

I'd like to mention that I won't require a lamp or color wheel, as my sole intention is to project laser light.

    Hello Ben,

    The DLP technology is a chipset solution which includes the DMD, a controller and Power management IC. You need all these components along with the firmware for operation.  The EVM provides a fast and efficient way to evaluate or run such experiments.  The other option would be to design your own drive electronic board using the controller and supporting components.  

    I believe your application will require controlling light at pixel level.  The DLP chipset targeted for 3D scan and machine vision do support pixel level control.

    The DLP3010EVM-LC or DLPLCR4500EVM will be suitable for your application.

    You can either mount the DMD on your optical bench using the mounting hardware in the EVM's optical engine or replace the LED in the optical engine by laser and use the optics of the engine.
