Scanning Mini-Chrom Monochromator with Operating Range 420 nm - 1.15 μ
The Scanning Mini-Chrom monochromator (SMC) is designed to be driven by stepping or servo controlled motors. No direct visual wavelength readout is provided. All models utilize a precision lead screw/sine bar mechanism to rotate the diffraction grating which sequentially positions the selected wavelength(s) at the exit slit. Rotation of the drive shaft in a clockwise direction proportionately increases the wavelength at the exit slit.
Scanning Mini-Chroms are used in applications requiring either single or repetitive scans of wavelength intervals or the sequential selection of discrete wavelengths. To prevent mechanical damage due to inadvertently exceeding wavelength limits, all Scanning Mini-Chroms are supplied with dual photosensors that function as high and low limit switches.
