FREEDOM HR-VISNIR / C-VISNIR

High resolution in a compact form factor

FREEDOM HR offers the perfect balance between compact size and high resolution in your instrument design due to the use of Ibsen Photonics’ unique transmission grating technology. The spectrometer is robust and almost athermal and can operate under demanding environmental conditions.

Furthermore, the FREEDOM HR spectrometers support many different detector systems which enables you to choose the best detector option for your specific application. FREEDOM HR even allows you to re-use already developed electronics and software for your favorite detector type.

The Freedom C offers an even higher resolution with a 4096 pixel detector.
