VS70-HSR & VS70-HDR

High Spectral Rate and High Dynamic Range Miniature Spectrometers

VS70 is a high performance compact fiber coupled spectrometer system covering wide spectral range of 200 to 1050 nm. This OEM optical module is built around Horiba’s
type-IV Aberration-Corrected Flat-Field Holographic Ion-Etched concave grating and is specially designed to easily adapt to a large variety of detectors and electronic drivers. This system is fitted with a custom variable order-sorting filter to eliminate higher orders.

The proprietary layout of the VS70 features a single-optics design for superior imaging, peak symmetry and resolution, sensitivity and low-stray light performance, for low-light applications (fluorescence, emission) and high-dynamic applications (absorbance, reflectance).

For OEM Industrial Applications

Ideal for industrial low-light applications such as fluorescence, emission, absorbance, and reflectance.
Examples:

Semiconductor plasma monitoring
Colorimetry
Blood and urine analysis
Liquid chromatography
Food moisture content analysis
Flow cytometry
