Qmini - Miniature spectrometer for industrial use

The Qmini from Broadcom is a miniature spectrometer designed for industrial applications and integration into systems.
With a choice of optical gratings in this matchbox-sized spectrometer, different wavelength ranges can be covered from 220 to 1100 nm. It is delivered ready for immediate use and has integrated electronics with short sensor readout times. Broadcom spectrometers are supplied with a software package for general applications.

A special SDK provides a library for the .NET environment and contains sample code for C++, Python, Delphi, LabVIEW, Matlab and others.

All device interfaces (USB, SPI and UART) are supported and can be easily integrated into existing applications.
