Meet the AvaSpec-Mini; a compact, versatile, USB-powered spectrometer, available in several versions. These compact units only have the size of a deck of cards, with excellent temperature and wavelength stability. These instruments are easy to take anywhere you like and are very well-suited for handheld applications.

Next-Gen successor arrived

After years of successful implementation with our valued customers, the AvaSpec-Mini Spectrometer is being retired and replaced by its next-generation successor; AvaSpec-NEXOS™.

The NEXOS™ spectrometer offers high-end performance with high speed, minimal stray light, and a high signal-to-noise ratio. All variations are compatible with Avantes light sources, accessories, and AvaSoft software. Learn more about the NEXOS™ and its advantages.

Next-Gen successor arrived; AvaSpec-NEXOS™

For an even more advanced and reliable solution, we invite you to explore the Nexos, the successor to the Mini Spectrometer. With enhanced capabilities and cutting-edge technology, the Nexos is designed to meet all your spectroscopy needs.

  • Lightweight and high-end performance spectrometer
  • Integration times of up to 9 μs
  • Minimal stray light as low as 0.1%
  • Strong signal-to-noise ratio of 375:1
  • Optimized for spectroscopy integration

Discover the NEXOS!

CMOS inside

The AvaSpec-Mini-CL series can be equipped with a 2048-pixel CMOS detector or our first-to-the-market 4096-pixel array. Enjoy the speed and enhanced native UV/NIR response of CMOS with an incredible resolution of up to 0.09 nm unavailable anywhere else. The low stray-light design allows stray-light levels from as low as 0.2%, and the fast response time boasts data transfer speeds as fast as 4.6 ms/scan and integration times ranging from 30 µs to 50 s.

For enhanced performance, we recommend you explore the AvaSpec-NEXOS. This product is the latest addition to our compact series and incorporates the very latest in technology.
