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.
At the heart of the STS is a 1024-element CMOS detector in a crossed Czerny Turner optical bench. The bench is distinguished by specially designed collimating and focusing mirrors and a 600 lines/mm groove density grating. Its optical design and advanced CMOS detector elevate STS to performance levels comparable to larger and more expensive spectrometers. For example, STS has 14-bit A/D resolution and has low power consumption of just 0.75 W. Also, with customization of the entrance aperture, optical resolution <1.0 nm (FWHM) is possible. This makes STS an attractive option for a wide range of applications.
