Full Spectral Analysis in a Tiny Footprint

Our new STS Microspectrometer is a remarkably small CMOS-based unit that is less than 50 mm square and weighs just over 2 ounces.

This ultra-compact spectrometer is ideal for OEM devices and provides full spectral analysis with low stray light and high signal-to-noise ratio.

STS boasts optical resolution of ~1.5 nm (FWHM) and is particularly suited for high-intensity applications such as LED characterization and absorbance/transmission measurements.

STS meets or exceeds optical resolution, stability, sensitivity and other performance criteria associated with larger, more expensive spectrometers. Plus, its built-in shutter makes taking dark measurements more convenient.
