New high resolution and ultra compact UV VIS NIR spectrometer - Qmini 2

RGB Photonics releases a new revision of the successful Qmini spectrometer. The updated product revision targets the market demand of high resolution spectrometers offering a very compact form factor for the wide spread wavelength range between 190 nm and 1100 nm. Furthermore, the product line received major enhancements in terms of electronics, connectivity and optical performance.

The new Qmini shares virtually the same form factor of it´s predecessor revision but receives major performance and functional updates including:


  • Spectra processing steps performed completely on the device
  • USB 2.0 High-Speed communication
  • Integration times down to 3 µs
  • Fast spectrum series function
  • On-device spectra storage


  • USB Type-C connector 
  • 30-pin auxiliary connector including communication protocols on demand:
    • UART
    • SPI
    • I2C
    • CAN
  • 10-bit digital-to-analoge and analoge-to-digital converter
  • 4 x low latency trigger input/output

Optical performance

  • Increased sensitivity
  • Thermal stability
  • Optical noise suppression / lower stray light
  • Guaranteed spectral resolution over the whole range
    • 0.3 nm UV version
    • 0.7 nm VIS / NIR version
    • 1.5 nm Wide UV / Wide VIS / VIS - NIR version

The full featured but yet compact composition of the new Qmini fits perfectly in any application environment where minimal size and a comprehensive set of features are vital. 

Applications such as process and quality control in biology, pharmacy, medicine, chemistry, material science and environmental measurement are typical use cases.
