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) with a 25 µm slit 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.
STS is available with a 10 cm fiber that has a 400 µm core diameter and can be configured with 10, 25, 100 or 200 µm slits.
Choose STS-VIS for 350-800 nm wavelengths or STS-NIR for 650-1100 nm.
OEM Ready
For OEM applications, the STS features a price that matches its size. We also provide volume discounts for OEMs who qualify*.
