Dear Reader,

With this newsletter, I want to make you aware of the newest addition to the FREEDOM family – the FREEDOM VIS-NIR spectrometer from Ibsen Photonics, covering 475-1100 nm in an ultra compact footprint.Freedom 02

Also, I have added another technical note to our collection of detector comparison notes. Thomas Rasmussen has yet again done some comparative measurements of Sensitivity and Signal-to-Noise on similar spectrometers using two different detectors – this time using the SONY ILX511B and the Hamamatsu S11639 CMOS. Please follow the link below to the technical note that summarizes the results. I hope you will find it useful.

Best regards,

Pernille Kennedy, Sales and Marketing Coordinator


[h3]FREEDOM VIS-NIR 475-1100 nm[/h3]

New ultra compact VIS-NIR spectrometer

FREEDOM VIS-NIR supplements the UV, VIS and UV-NIR spectrometers in the FREEDOM series of products. 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 new FREEDOM VIS-NIR are: high efficiency across the 475 – 1100 nm range, ultra compact size of 25 x 48 x 16 mm, robust and athermal performance, and flexibility in choice of detector and electronics.

FREEDOM VIS-NIR comes in three standard variants with either a low cost front-illuminated CCD, a high dynamic range NMOS, or a low noise back-thinned CCD, however, more detector options are available upon request.
