Compact spectrometer for irradiance (STS-RAD)

/ Spectrometers

Amazing STS spectrometer radiometrically calibrated for irradiance measurements with direct-attach cosine corrector

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 production line.
