10.3.3 Cleaning the cell mirror
If contamination makes its way into the cell and accumulates on the internal optics, a DC spectrum power range
exceeded fault will result. If mirror contamination is suspected, contact Service before attempting to clean the
mirrors. If advised to do so, use the following procedure.
INVISIBLE LASER RADIATION

The sample cell assembly contains a low-power, 10 mW maximum, CW Class 3b invisible laser with a
wavelength between 750-3000 nm. Never open the sample cell flanges or the optical assembly unless the power
is turned off.

This procedure should be used ONLY when necessary and is not part of routine maintenance. To avoid
compromising the system warranty, contact Service →  before cleaning mirrors.
