STS Microspectrometers / Spectrometers
Amazing full-spectrum performance in a tiny footprint
STS Microspectrometers summary
The STS introduces a family of ultra-compact spectrometers, ideal for embedding into OEM devices. At just 40 mm x 42 mm x 24 mm, the STS provides full spectral analysis with low stray light, high signal to noise ratio and optical resolution of ~1.5 nm (FWHM).
The STS is an especially attractive option for high-intensity applications such as LeD characterization and absorbance/transmission measurements.
At the heart of the STS is a CMOS detector in a crossed czerny Turner optical bench. The bench is distinguished by custom-molded collimating and focusing mirrors and a 600 lines/mm groove density grating that projects spectra onto the detector.
These microspectrometers are available in UV-Vis-NIR wavelengths.

We offer STS models for 190-650 nm (STS-UV), 350-800 nm (STS-ViS) and 650-1100 nm (STS-Nir) applications.
Each unit has a fixed optical bench configuration. custom configurations are available for high-volume applications. To optimize signal collection efficiency and improve reproducibility, STS utilizes a fixed-fiber design. The fiber has a 400 µm core and is 10 cm in length. The STS is fully operational in SpectraSuite spectroscopy software. operating and development software are priced separately.
