MiniVS70 Compact High Resolution CMOS or CCD Spectrometer

Compact High Resolution CMOS or CCD Spectrometer

MiniVS70 is the latest evolution of the cost-effective high performance family of mini-spectrometers from HORIBA Scientific. This MiniVS70 system for industrial applications uses a modified miniaturized VS70 optical engine which is optimized for the UV-VIS-NIR spectral range. The MiniVS70 is based on a high performance aberration corrected concave grating fitted with a custom order-sorting filter to eliminate higher orders.

This platform is specially designed to easily adapt to a large variety of detectors and electronic drivers. The optical design is optimized to minimize stray light and maximize optical performance. The MiniVS70 outperforms competitive mini-spectrometers based on front-illuminated CMOS linear sensors or low-cost back-illuminated CCDs.
