The Horiba / Spex 1681B 0.22m Spectrometer is a compact general-purpose spectrometer that can deliver high purity radiation without sacrificing throughput. Its internal drive circuitry couples directly to a Spex Minidrive-2, CD2 Compudrive scan controller, or the DM3000 spectroscopy computer. The Spex 1681B has a four-digit wavelength counter that displays the central wavelength of light that will pass through the spectrometer. This counter is calibrated in nanometers. Spectral range scans are done with a drive system that is that is linear in wavelength. Gratings can be rotated in steps as small as 0.02 nm (standard grating).
