Ultra Compact and Broad Range Spectrometer

InVizU Cube (Infrared-Visible-Ultraviolet) is the latest evolution of the ultra compact, high performance spectrometers from the HORIBA Scientific OEM team. This dual system for industrial applications uses a modified miniaturized VS70 optical engine optimized for the UV-VIS spectral range along with the VS20 optimized for the NIR spectral range. The InVizU Cube is based on high performance aberration corrected concave holographic gratings fitted with custom multi-area 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 InVizU Cube outperforms current generation of broad range mini-spectrometers thanks to its compact sleek design, high sensitivity, flat spectral response and resolution.
