The camera’s advanced design permits high speed download via the USB 3.0 connection to the control computer. The Aluma AC2020BSI uses the Gpixel GSENSE2020BSI-H CMOS sensor with 4 million pixels at 6.5 microns in a 2048 x 2048 array. The sensor measures just over 13.3mm square. The Aluma AC series has powerful two stage cooling and supports optional water cooling. Aluma AC cameras can be operated directly from a 12VDC 8A power supply.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign features include:\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch3\u003eBack-Illuminated Sensor:\u003c\/h3\u003e\n\u003cp\u003eIncredible sensitivity!
