Model: ALEX-s 1k256、ALEX-s 2k512
Brand: greateyes

Born in Berlin, ALEX is the latest camera developed by the German company greateyes, designed for spectroscopy and imaging in the extreme ultraviolet, vacuum ultraviolet, and X-ray energy ranges.

ALEX integrates the most advanced low-noise electronic systems and ultra-low-temperature cooling technology while maintaining a compact and lightweight design.

The new design allows flexible selection of readout speeds from 50 kHz to 5 MHz.

The 18-bit analog-to-digital conversion utilizes the full dynamic range of the CCD sensor to achieve better performance and a higher signal-to-noise ratio.

To match the needs of different applications, the camera offers a variety of sensor types for users to choose from.

Additionally, ALEX's low noise makes it an ideal camera for extremely weak signal conditions, bringing unprecedented possibilities to your spectroscopy and imaging research.
