Product Description
ASI533MC Pro
Camera Sensor
▶IMX533
1” square sensor
The IMX533 is a 1-inch, 9MP CMOS image sensor in a square format with a 3.76 um pixel size, capable of producing frames at 20 frames/sec in 14bit 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.
IMX533 backlit sensor
Sony’s back-illuminated CMOS image sensor improves sensitivity and noise reduction – the key factors to enhancing image quality, while radically realigning their fundamental pixel structure from front-illumination to back-illumination. It has retained the advantages of CMOS image sensors such as low power consumption and high-speed operation.
With a conventional front-illumination structure, the metal wiring and transistors on the surface of the silicon substrate that form the sensor’s light-sensitive area (photo-diode) impede photon gathering carried out by the on-chip lens. A back-illuminated structure minimizes the degradation of sensitivity to optical angle response, while also increasing the amount of light that enters each pixel due to the lack of obstacles such as metal wiring and transistors that have been moved to the reverse of the silicon substrate.
Sony has newly developed a unique photo-diode structure and on-chip lens optimized for back-illuminated structures, that achieves a higher sensitivity and a lower random noise without light by reducing noise, dark current and defect pixels compared to the conventional front-illuminated structure.
Camera Performance
Low read-out noise, high dynamic range.
Zero Amp Glow
Traditional CMOS sensors produce a weak infrared light source during operation quite often seen in the corner of uncalibrated images as the tell tale signs of ‘amp glow’. As the ASI533MC PRO uses zero amp glow circuitry, you won’t have to worry about amp glow even when using high gain, long exposure imaging.
With amp glow – exposure 300 second exposure:
ASI533 frame with no amp glow – Exposure 300 seconds:
Dark current
Note: We recommend using an external 12V power supply to power the camera instead of USB 3.0/2.0 only
DDR Memory Buffer
The ASI533MC PRO is equipped with a USB 3.0 interface, and even in 14bit mode, can reach 20 frames per second. The 256MB DDR3 memory ensures stable downloading of frames with increased USB speeds.
ASI533MC Pro – ASI183MC Pro Comparision
The ASI533MC PRO features SONY’s latest back illuminated IMX533 sensor, with a 1-inch square, 9.07MP sensor that is ideal for astronomical photography needs and can be considered as the latest iteration of the venerable ASI183MC Pro.
As you would expect this latest generation camera not only retains key features of the ASI183 series such as an attractive QE figure, high frame rate and along with other excellent characteristics of the ASI183 cameras, but also now includes new and improved features such as zero amp glow, extreme low read out noise (as low as 1.0e), 3.76 microns pixel size and an improved 2 stage TEC cooler giving enhanced cooling capabilities.

Couple of posters have already wished for an uncooled version. The answer was: “Maybe”. I would consider to use it in EAA.

Sorry we do not have plan for uncooled 533 now.

Hoping to see more square format cameras in the future, this would seem to be the most efficient use of image circle area and makes the job of mating the correct flattener and reducer combination in the optical train. Do you see more square format cameras coming in the future?

Hi, can we assume, absed on histograms on ur site, that the “unitary” gain for this cam should be the level 100 ?

Katherine Tsai – :
Yes.
Unity gain for ASI533 is 100.

Katherine Tsai – :
You can confirm it with Canada dealer.

Sony made this amazing CMOS both in Color and in Mono. Back illuminated mono sensor is extremely useful for scientific applications due to the extensive sensitivity in blue and UV. Is there a monochrome model planned?

Dear ZWO, i placed the order yesterday through your website for the ASI533MC. I don’t know the waiting list and how many other back orders are in front of me but it would be nice to have a rough idea when it will be shipped. Can you tell? Thanks!

Loek Baede – :
Dear friends,
why do you say this new camera has a 1″ sensor, when the actual diagonal is 15.968mm ? A bit confusing.
Best regards,
Loek

Katherine Tsai – :
Actually, the diagonal of 1″ sensor is 16mm.

Michael Hettrick – :
As tabulated by Dr. Robin Glover (the developer of SharpCap) on the internet, the sky background from even the darkest sites (Bortle 1) on the planet, exceeds the uncooled dark current for this IMX533 sensor. Combined with the absence of ampglow (and thus any need to take dark frames), there is zero technical reason to cool this chip, or therefore to pay for such a cooling system. Please make an uncooled camera incorporating this chip, which will of course have the advantages of being less expensive, smaller and lighter.

There are still many dark noise so darks are essential.

When would pre-orders ship?
I’m on the fence between this new cutting edge ASI533MC-P and the ASI294MC-pro for EAA.

ZWO ASI Camera – :
Maybe.
So far ASI533 is the best camera for novices in DSO.
