From optek-Danulat, Inc.

Optek process photometers use three superior grade light sources in conjunction with precision filters and photo components. A wide selection of optical components allows optek to configure a process analyzer to measure within a specific portion of the electromagnetic spectrum. This enables a diverse range of process measurement applications.
