Our compact high resolution spectrometers offer the perfect balance between compactness and performance

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-VIS offers the best possible resolution due to a 4096 pixel detector.

Test it yourself!

We understand that it can be hard to judge the performance of a spectrometer just from the data sheet. Therefore, we offer a time limited loan of a demo unit to customers that meet certain criteria.
