ATP5020 UV-Vis Spectrometer employs the ultra-high performance, high-sensitivity, high resolution, and cost-effective model. The award-winner spectrometer is called cooled Maya, it can even replace Maya and QE65 in SNR, sensitivity, and resolution. It's ideal for Raman system well. It uses 2048 x 64 pixel, a back-thinned CCD array, TE-cooled down to -10 ℃. Sensor noise is reduced, and SNR is almost 2 times higher than others. Increased reliability can remain measure result do not change with temperature.
Customized design of ultra-low noise CCD signal processing circuit built inside, Noise is lower can 3 counts is ahead of records in the industries. 
ATP5020 is designed with SMA905 optic fiber entrance connector or free space, and it outputs spectral data via USB2.0/UART
