DLP4710: Spectral limitations of DLP and development pla

Part Number: DLP4710

I am planning to use the DLP7410 in a spectrometer. I know that the working spectral range is ~400 to 700 nm, but what limits the longer wavelength.

Is it the AR coating on the cover  glass or is it related to the Mirrors themselves.

Also, I know that there is a development module DLPDLCR4710EVM-62, but this is more elaborate than I need. Is there a simpler platform with just the DLP and driver chips?

    Hello Bob,

    What wavelengths are you targeting? TI does offer product for operating in the 400-420 nm wavelengths. (Near-UV products (400 to 420 nm) | TI.com) These limits for the 4710 are based on product design and target application, the window coating is not a factor. 


    In regards to your second questions, all of our EVMs are fully built systems to allow users to learn and develop with out systems. They are not meant for end devices, however we provide all the necessary reference designs and bill of materials so that users may design their own custom board. 

    Best,
