UV-NIR spectrometer and long pulse compression gratings



The FREEDOM combines compact size, cost efficiency, and high performance with flexibility in the choice of detector system. These benefits make FREEDOM especially well-suited for integration into portable and handheld instruments.

The key benefits of the FREEDOM UV-NIR are high efficiency across the complete 190 – 1100 nm range, ultra compact size of 50 x 50 x 15 mm, robust and athermal performance, and flexibility in the choice of detector and electronics.

The high broadband efficiency is obtained with an innovative transmission grating, developed and manufactured by Ibsen Photonics specifically for the FREEDOM UV-NIR. In contrast to typical blazed gratings, this grating provides nearly constant diffraction efficiency over the 190 – 1100 nm range for both polarizations. The small size, athermal performance, and robustness make the UV-NIR spectrometer ideal for process control out-of-the-lab environments as well as handheld and portable instruments.

FREEDOM UV-NIR comes in two standard variants with either a low cost front-illuminated CCD or a low noise back-thinned CCD but, more detector options are available upon request.
