Miniature spectrometer for industrial use
Broadcom offers several mini spectrometers for measurements in the UV/VIS/NIR between 190 nm – 1700 nm, designed for industrial needs. The spectrometers are ready for immediate use and have integrated electronics with short sensor readout times. Broadcom’s spectrometers come with a software package for common applications. A dedicated SDK provides a library for the .NET environment and includes 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 application.
