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.

Key features:

  • 190 nm to 435 nm wavelength range

  • Numerical aperture of 0.11

  • Resolution for HR-UV / C-UV: 0.27 nm/0.15 nm (typical)

  • Footprint of 61 mm x 64 mm x 19 mm

You can couple into your spectrometer both by free space or via fiber.

You also have several options for reading out over a standard interface like USB or SPI with our different electronics options, which you can see here.

Uncooled spectrometers FHU-101/315/380 and FCU-109:

The FREEDOM HR-UV/C-UV spectrometers are using the DISB electronics with either an SPI or USB interface. The communication with the spectrometer can be done using low-level read-write commands to the FPGA on the board.

If your spectrometer is equipped with the DISB-USB Bridge electronics with the FT4222 chip, you can find some software programming examples here.

Which spectrometer to use?

Do you need to evaluate a spectrometer for your next project?
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.
