Original question:

DLPLCR65EVM: Project the DLP image with an objective lens

PCA9515A: V-7000 VIS

Part Number: PCA9515A

Hi there,

We are attempting a similar thing to other members in thread.

We have the V-7000 DMD device on a breadboard with illumination from a 1mm square fiber connected to a laser. We are able to collimate the 

light source onto DMD surface nicely (although this maybe not best practice?) The DMD is rotated at 45 degrees and the illumination is set to 24 degrees, however 

the projected image is coming out at an angle. If we adjust illumination to 12 degrees it straightens up, but we think this isn't the correct angle for the illumination?

Sorry if this all sounds a bit pedestrian, but this is new territory for us. The final goal is to feed the image into an objective on the Nikon FN1 microscope.

Any help/advice would be greatly appreciated.

Mark

    Hi Mark,

    Not pedestrian at all, but at our team TRX, we do not deal with optical related problems. Have you tried contacting the optical team to further analyze your request? 

    The device you selected (PCA9515A) is an I2C buffer made for extending an I2C bus that is heavily loaded nearing the parasitic bus capacitance limit (usually 400pF), allowing for further bus functionality. 

    I believe the team you want to contact is over at HSSC (high-speed signal conditioning). 

    I have moved the thread over to their team.

    Regards,

    Tyler
