VS70-MC Spectral Coverage

Miniature Multi Communication UV-NIR Spectrometer

VS70-MC (Multi Communication) is a high performance compact fiber coupled spectrometer system covering wide spectral range of 200 to 910 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 an integrated order-sorting filter to eliminate higher orders.

The proprietary layout of the VS70-MC features a single-optics design for superior imaging, peak symmetry, flat spectral response, high resolution, high sensitivity and low-stray light performance. This system is very well suited for life sciences and semiconductor industry applications such as OES, reflectometry and quality control.
