- Connects to any computer via standard RS 232 interface
- Double grating turret allows for a broad spectral range coverage
- May be factory configured as a monochromator or a spectrograph
- Scans in both directions and in nanometers, Ångstroms, microns, wave-numbers, or eV
- Change slits on the fly
- Monochromator may be factory configured for right angle or straight through beam path.
- Suitable for fluorescence, radiometry, process control, colorimetry, tunable filtering, Raman spectroscopy, among others.


Single piece base construction, direct grating drive, and anti-backlash gearing ensure this unit is rugged and stable enough for demanding applications. Loaded with SP Optics and able to hold two high quality gratings, the CM110 is ideal for spectrometry in the UV to IR spectra.
