The ZWO ASI 533MM is a monochrome un-cooled camera for planetary imaging and EAA and features a 9MP back-illuminated CMOS sensor with 91% quantum efficiency at 460nm.

 

 

The ZWO ASI 553MM contains the Sony IMX533 CMOS monochrome sensor which has a diagonal of 15.99mm and a resolution of 9 MP. The Sony STARVIS back-illuminated sensor technology is highly sensitive and has exceptionally low read noise.

ZWO cameras incorporate a 256MB DDR3 memory buffer that improves data transfer reliability and it minimizes amp-glow caused by slow data transfer speeds.

 

 

A higher QE means more of the light is converted into signal. The ASI 533MM has a maximum QE of 91%.

The USB 3.0 Port provides 5Gbps bandwidth and lets the camera run at 20fps  at full resolution.

 

ASI 533MC

The dark current of the ASI533MM is extremely low, based on our test results. 

 

 

Traditional CMOS sensors emit a weak infrared light and quite often it is seen in the corner of uncalibrated images. This is called "amp glow". The ASI533MM uses a zero amp glow circuitry which eliminates the problem, even when using high gain and a long exposure.

With amp glow – exposure of 300 seconds:
