Thermo Vision Colorado Monochromator Overview

Jarrell Ash began offering quality products for light-based research in 1942. Thermo Vision Colorado took over Jarrell Ash's monochromator, spectrograph, and gratings business in 1991. If you have inherited a vintage Jarrell Ash instrument, we still support them. You can configure a ruggedly built system with the features you need at an economical price. The salient features of the five monochromators we offer are shown in the table.
