The Qmini is the most flexible OEM spectrometer in Broadcom’s portfolio. It is available in six different spectral configurations between 190 – 1100 nm and is the ideal tool for tight process probes where space is limited. Featuring super-fast read out times, different serial interfaces like USB, SPI and UART as well as several communication protocols, the matchbox-sized Qmini fits into smallest process pipes and handheld spectrometer systems for point-of-care detection.
Spectral shifts down to a deep UV spectrometer module are possible, please contact us for your OEM design with excellent UV response.
