The STS Microspectrometer is available in standard models with 350-800 nm and 650-1100 nm wavelength coverage. Customization of wavelength range, entrance aperture, and other optical bench accessories is available for high-volume and OEM customers. Also, unlike other microspectrometers, STS has a built-in shutter for making dark measurements. Operating software is priced separately and provides a full range of spectroscopic functions as well as control of the shutter. Packages for developing customized software for STS are also available.
