Avantes is excited to release the next generation of AvaSpec-Mini spectrometers with CMOS detectors and advanced electronics and communications. Like the original AvaSpec-Mini, the CL series is only the size of a deck of cards, with excellent temperature and wavelength stability. This instrument is easy to take anywhere you like and is very well suited for handheld applications.

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.
