Hi Richard, Thanks for thinking of me ;-)
Unfortunately, HP did not make me privy of the materials in use within this scanner, nor did I dismantle mine to test the options. As someone else suggested, contacting HP's tech people might prove most effective, as they might know the answers you are seeking. I have been told the lens is glass not plastic. All front surface mirrors are very vulnerable to scratching, so be very careful when cleaning them.
