Product description

[4000645227004]

Entry-level camera for deep space photographyASI533MC PRO uses SONY back-illuminated IMX533 sensor,With 1-inch square format is particularly suitable for astrophotography needs;Can be considered as a fully upgraded and iterative product of the ASI183 series.
As an iterative product, ASI533MC PRO not only As an iterative product, ASI533MC PRO not only retains the high-quality features such as high QE and high frame rate of ASI183, but also has no glow, read noise as low as 1.0e, pixel size of 3.76 ?, and level 2 TEC cooling guarantee; Especially recommended for deep space photography users.
One inch square format:IMX533 is 1 inch, aspect ratio 1: 1, pixel size 3.76 ?, 9 million pixel CMOS image sensor, in ADC 14bit mode, it can output 20 frames per second resolution and read noise as low as 1.0e. SCMOS or EMCCD sensors are comparable, so they are suitable for image requirements that require high definition and low noise.

IMX533 back-illuminated sensor:The traditional CMOS sensor has a metal cable layer on the photodiode. When light passes through the cable layer, it will be blocked or reflected, resulting in the photodiode only absorbing 70% or less of the light;The back-illuminated sensor has the metal wiring layer and the diode reversed in position, and the light reaches the photodiode without blocking. The absorption rate is higher and the imaging quality is higher.

Comprehensive upgrade: As an iterative product, ASI533MC PRO has been comprehensively upgraded compared to ASI183 series:

Camera curve: low readout noise, high dynamic rangeCamera curve: low readout noise, high dynamic range
Non-glow process:Traditional CMOS sensors generate weak infrared light when they are powered on. When the camera is in the exposure process, it is equivalent to a light source, which affects the overall imaging quality. The ASI533MC PRO uses a non-glow process, regardless of long exposure or high gain You do n? have to worry about photo quality.
Quantum efficiencyAfter our calculation, the peak quantum efficiency of ASI533MC Pro is greater than 80%

Dark current

Secondary TEC refrigeration guarantee:The 2 level TEC cooler can lower the CMOS sensor to below 35 ?ambient temperature (based on the temperature test result of 30 ?, reduce the generation of dark current, and even with long exposure time of hundreds of seconds, the noise is very small.Note: The lower the temperature, the smaller the temperature difference?USB3.0 & 256M DDR3 memory:ASI533MC PRO is equipped with USB3.0 transmission interface, even in ADC 14bit mode, the output frame rate can reach 20 frames / second;In addition, 256M of DDR3 memory can also ensure that the camera can ensure stable data transmission during long exposures without dropping frames, and can also reduce the hardware requirements of the shooting computer.
