Compact Spectrometers with Broad Wavelength Range

 

Ibsen has developed an extreme broadband grating technology and offers a series of ultra-compact, broadband spectrometers based on these – the FREEDOM UV-NIR (190-1100 nm) and the FREEDOM UV-VIS (190-850 nm) which are ideal for high performance portable solutions.

Broadband Spectrometers – FREEDOM UV-VIS and VIS-NIR

Compact UV-VIS-NIR broadband spectrometersThe FREEDOM broadband spectrometers combine compact size, cost efficiency, and high performance with flexibility in the choice of detector system and electronics. These benefits make FREEDOM especially well-suited for integration into portable and handheld instruments.

The key benefits of the FREEDOM UV-VIS-NIR are: high efficiency across the complete 190 – 1100 nm range, ultra compact size of 48 x 54 x 16 mm, robust and athermal performance, and flexibility in choice of detector and electronics.

The high broadband efficiency is obtained with an innovative transmission grating, developed and manufactured by Ibsen Photonics. In contrast to typical blazed gratings, this new grating provides nearly constant diffraction efficiency over the 190 – 1100 nm range for both polarizations.

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

The FREEDOM UV-VIS spectrometers are, as an example, ideal as a UV detector in a High Pressure Liquid Chromatography (HPLC) system.

Why FREEDOM UV-VIS is well suited for HPLC

The FREEDOM UV-NIR broadband spectrometers have a wide wavelength range and are therefore ideal if the spectrum you want to measure is spread out. This is, for example, the case with the characterization of coatings and thin films, as seen on e.g. displays and on glass panes.
