For measurements in regulated industries, ATR accessories need to be
validated periodically. The Middleton Spectral Vision ATR Validation Standards
serve to test the functioning and reproducibility of ATR accessories
and systems, without contaminating the ATR crystal surface.
ATR accessories can be tested periodically using the ATR Validation
Standard. The material of the Standard is rugged and flexible, thus the
ATR element does not leave an imprint on the Standard. Other materials
used to test ATR accessories, such as polyethylene are compressed and
destroyed during the testing, whereas the MRC-910-ATR can be used
repeatably over a long period of time.
