Scanning Digital Mini-Chrom Monochromator with Operating Range 420 nm - 1.15 μ
Scanning Digital Mini-Chrom Monochromator
The Scanning Digital Mini-Chrom Monochromator (SDMC) includes an integral stepping motor which can be controlled by a calibrated drive such as the Optometrics PCM-02 via a 15-pin connector. The SDMC is similar to the Digital Mini-Chrom in that it includes a four digit counter for visual wavelength readout and a dial for manual wavelength selection.
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. For near infrared model (06), the four digit counter reading must be doubled, to 2 nm per division.

The Scanning Digital Mini-Chrom can be used for all applications that require the convenience of an integrated visual wavelength readout and manual wavelength tunability, as well as applications requiring computer controlled scanning to a selected wavelength or routine. To prevent mechanical damage due to inadvertently exceeding wavelength limits, all Scanning Digital Mini-Chroms are supplied with dual photosensors that function as high and low limit switches are included for use in the motorized scanning mode.
