Hi all,

I was just wondering if anyone knew what the exact focal length of the lens is in regard to the TCS3200-DB Color Sensor?
Calculating from the information given in the sensor documentation (http://www.parallax.com/Portals/0/Downloads/docs/prod/acc/TCS3200_doc.pdf) I get roughly 22cm could anyone confirm this?

Thanks in advance.

    Welcome to the Parallax forum!

    The lens currently supplied with the TCS3200-DB has a focal length of 5.4mm.

    Cheers Phil,
    Seems like my calculations were slightly off (my method was really dodgy so not a big surprise)
    Thanks for the quick reply.
