Currently, every series of Sarspec’s spectrometers offer every user the possibility of adding filters at the entrance of the spectrometer, after the slit. The slit works simultaneously as a filter holder, but while the slit is permanently attached to the holder, it is possible to use multiple filters with one holder as it is held through a threaded and detachable part. This offers great flexibility to all spectrometers and can mean a significant added value for specific applications.
This way, with an easy manual operation, you have the possibility of selecting a specific wavelength, band or range, blocking undesired wavelengths, band or range, or performing signal attenuation, among others. With a wide range of filters available on the market, the possibilities are endless. To match the holder dimensions, the filters must have a maximum of 6.35 mm diameter and 2 mm thickness.
