Optometrics

The Standard Mini-Chrom Monochromator is a manual unit which utilizes a micrometer for wavelength selection and readout. Turning the micrometer causes, via a precision sine bar drive, rotation of the diffraction grating which positions the desired wavelength at the exit slit.

Wavelength is read directly from the micrometer at 1 nm per division in models 01, 02, 03, and 04. Wavelength readout for near infra-red models (05 and 06) is 2 nm per division.

Applications

They are used in a variety of physics, chemistry, engineering and the life science applications that require a small yet high performance manually tuned monochromator for precision wavelength selection.
