Spectral Evolution Manufactures the Most Reliable and Accurate UV-Vis-NIR Field-portable Spectrometers & Spectroradiometers
We value your time.
By using only photodiode arrays and fixed grating systems, we increase the system’s sensitivity and reliability. There are no moving parts to drift or malfunction during your mission-critical work. We constantly look for ways to make our instruments and software the easiest to use with one-touch autoexposure, auto-dark shutter, auto-ranging controls, and easy software pulldown menus.
We value your mobility.
Without sacrificing ruggedness, our systems are small and lightweight. Portable units are powered with high-capacity lithium-ion batteries and are Bluetooth compatible, so there are no extra cords or cables to restrict your work. Operating our system only requires a small laptop or tablet to keep your travel load as light as possible.

Given its high resolution, ease of use, and clean data (we collected data with a lens and not a contact probe), the PSR+ was incredibly useful in the field for snow/ice applications.

With a range of 280nm-1900nm the Spectral Evolution SR-1901 is an extremely versatile, lightweight and simple instrument for many microbiological applications.

Very satisfied with the instrument (PSR-1100f) and it’s very stable compared to other field spectroradiometers.
