The Ocean Optics STS Microspectrometer is therefore suitable for embedding in OEM devices and reportedly works as well as larger systems, offering a full spectral analysis with low stray light, high signal to noise (>1500:1) and typical optical resolution of ~1.5 nm full width at half maximum(FWHM).
It incorporates a 1024-element CMOS detector in a crossed Czerny Turner optical bench, which has specially designed collimating and focusing mirrors and a 600 lines/mm groove density grating. STS has 14-bit A/D resolution and has low power consumption of just 0.75 W.
STS is suitable for a range of visible and near-infrared (VIS-NIR) applications including characterisation of LEDs and absorbance/transmittance of various samples and can be used in OEM applications where one or more wavelengths are being monitored and reproducible results are necessary.
The STS Microspectrometer is available in standard models with 350-800 nm and 650-1100 nm wavelength coverage. The wavelength range, entrance aperture and other optical bench accessories can be customised. Unlike other microspectrometers, STS has a built-in shutter for making dark measurements.
