The planetary camera ASI533 features Sony's latest back illuminated IMX533 sensor, high sensitivity, and zero glow. With a 1" square sensor format, it is ideal for astronomical photography.
1" Square Frame
The IMX533 is a 1" square format that is ideal for astronomical photography. With a 3.76 um pixel size, the ASI533 is capable of producing frames at 20 frames per second in 14 bit mode. Read out noise is as low as 1.0e which makes it comparable to SCMOS or EMCCD sensors and highly suitable for high definition, low noise imaging.
ASI533 can be regarded as an upgrade product of ASI183 series. It's equipped with SONY STARVIS CMOS sensor, which has a better effect when shooting at night. It has the advantages of zero amp glow, a large full well, low readout noise, and a high dynamic range.
USB .0 & 256M DDR3 Memory
The ASI533 is equipped with a USB 3.0 interface, and the 256MB DDR3 memory ensure stable downloading of frame with increased USB speeds and effectively reduces the glow caused by slow readout speed.
Zero Amp Glow
ASI533 uses a no-glow circuity to ensure the best quality images regardless of gain or exposure length.
Compared with ASI183 series, ASI533 has been fully upgraded.
Low read noise, high dynamic range.
Based on ZWO's calculations, the peak quantum efficiency of the ASI533MM is greater than 91%.
Dark Current Noise
The ASI533 camera sensor is equipt with a protective window, with a diameter of 32mm and a thickness of 2mm. ASI533 uses an AR coated filter.
