Dear Reader,

With this newsletter, I want to make you aware of the new FREEDOM UV spectrometer from Ibsen Photonics, covering 190-435 nm in an ultra compact footprint.

Also, I have had problems finding direct comparisons between typical detectors used for diode array spectrometers. Therefor
e, we did some comparative measurements of Sensitivity and Signal-to-Noise on similar spectrometers using two different detectors – the SONY ILX511B and the Hamamatsu S10420 BT-CCD. Please follow the link below to a technical note summarizing the results. I hope the results will be as useful to you as they have been to me.

Best regards,
Thomas Rasmussen, VP Sales and Marketing

[h3]FREEDOM UV 190-435 nm[/h3]

New ultra compact UV spectrometer

The FREEDOM platform combines compact size and cost efficiency with high performance and flexibility in choice of detector system. Due to its robustness and thermally stable operation, the FREEDOM UV spectrometer is especially well suited for integration into high performance industrial instruments.

The ultra compact size of only 25 x 48 x 16 mm makes FREEDOM one of the smallest spectrometers on the market. Despite the compact size, the spectrometer provid

es a low stray light level and high efficiency due to the use of Ibsen Photonics’ in-house produced transmission gratings. Ibsen is one of few companies that can supply high efficiency transmission gratings in the UV, since we use pure fused silica as substrate for our gratings. Optical resolution can be as good as 0.5 nm and the f-number (f/3.1) is among the best for ultra compact spectrometers on the market.

FREEDOM UV covers 190 – 435 nm and supports several commonly used CCD, BT-CCD, and MOS detectors.

Comparison of SONY ILX511B CCD and Hamamatsu S10420 BT-CCD for VIS Spectroscopy

The purpose of this technical note is to provide some objective information that we think is useful for our customers in deciding which detector type to choose. The technical note compares sensitivity and SNR for the two detectors.
