ATP5040 uses 4096pixels, other parameters almost the same as ATP5020, it 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, a back-thinned CCD array, TE-cooled down to -10 ℃. Sensor noise is further reduced, and SNR is almost 2 times higher than others. Increased reliability can remain measure result unchanged 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. 
ATP5040 is designed with SMA905 optic fiber entrance connector or free space, and it outputs spectral data via USB2.0/UART
