AvaSpec-Mini(CL): CMOS Inside

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, though 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.

Designed and manufactured in the UK, the DS5 provides a modern, user-friendly and accurate UV-Vis spectrophotometer for a wide range of sample types and measurements.

Utilising a dual lamp and Czerny-Turner configuration monochromator, the DS5 features a compact, reliable and high throughput optical system which ensures impressive spectral performance. Additional benefits include stray light, baseline flatness, wavelength and photometric accuracy and reproducibility.

Application Note – “Transmission and Absorbance Measurements of Liquid Samples”

The DS5 can be used for absorbance measurements, an example of the type of research which can be carried out can be found in our application note “Transmission and Absorbance Measurements of Liquid Samples”. You can download the full application note here.
