The Standard Mini-Chrom is a manual unit which utilises a micrometer for wavelength selection and readout. Turning the micrometer head causes, via a precision sine bar drive, rotation of a diffraction grating, which delivers the desired wavelength to the exit slit. The wavelength value is obtained by reference to the micrometer head reading.
To read and thereby select a specific wavelength of interest, directly, in nanometres, from a counter then opt for the Digital Mini-Chrom series. Nine models are offered, spanning the 190 nm to 2.2 µm spectral range.
The wavelength on all Digital Mini-Chroms can be selected and read to an accuracy of 0.2 nm.
Mini-Chroms are used in physics, chemistry, engineering and the life sciences for research, development and teaching and generally in applications that call for a small, inexpensive yet high performance monochromator.
