TMc150 Monochromator

The TMc150 single monochromator represents an exceptionally compact measurement solution adapted to measurement where lower spectral resolution be required.

Compatible with the full range of sources, detectors and accessories of the Bentham portfolio, the TMc150 monochromator fits in the smallest of spaces in a measurement setup and is well suited for integration into an OEM system.
