Digital Mini-Chrom Monochromator with Operating Range 190 - 650 nm

Digital Mini-Chrom Monochromator

The Digital Mini-Chrom Monochromator (DMC) is a manually operated monochromator that utilizes a digital counter for wavelength selection. Rotation of the dial causes, via a precision lead screw/ sine bar mechanism, rotation of the diffraction grating which positions the selected wavelength at the exit slit.

The wavelength on all digital Mini-Chroms can be selected and read to 0.2 nm. Wavelength is read directly in nanometers (nm) from a counter on models 01, 02, 03, 04 and 05. Near infrared model (06) requires the counter reading to be doubled.

Digital Mini-Chrom monochromators are used in a variety of applications that require a small yet high performance manually tuned monochromator. They are used in physics, chemistry, engineering and the life sciences applications where a low cost manually tuned device for precision wavelength selection is required.
