VS70 OEM

Overview

This new OEM Optical module consists of a compact Versatile Spectrograph coupled with a multi-channel array detector.

The VS70 is a configurable, high performance spectrograph that can be customized for a variety of OEM
applications in the fields of analytical chemistry, medical analysis, semiconductors, process monitoring and many others. The VS70 was specially designed to easily adapt to a large variety of detectors and electronic drivers. The optical design has been optimized to minimize stray light and maximize optical
performance.

The VS70 is based on a high performance aberration corrected concave grating fitted with a custom
variable order-sorting filter to eliminate higher orders.

* Depending on the position and the type of the array detector used.

(*) Typical Linear dynamic range:
Because the A/D dynamic range (14 bits, 16 bits...) of the converter alone is not necessarily representative of the full detector system dynamic range, we measure this typical signal to noise ratio as the linear full well capacity (full dynamic) divided by the readout noise, where the linearity is better than 1%.
Please call or email us to discuss your signal to noise requirements in your application.

(**) Need High Dynamic Range?
Our spectrometers can be fitted with other Photo Diode Arrays, such as the Hamamatsu PDA S3904-1024 for a linear dynamic range of up to 12,000:1 for example.

(***) Need High Sensitivity for Fluorescence or Raman Applications?
We offer OEM low cost electronics for these high performance CCD detectors: Hamamatsu S9840 high UV sensitivity front- illuminated CCD, Hamamatsu back thinned CCD S7031-1006 and E2V high end CCD chips (front- illuminated, lumogen coated, back thinned, open electrode...).
