ASI533MC-Pro Camera with Sony IMX533 9MP CMOS image sensor in a square format with a
3.76 um pixel size, capable of producing frames at 20 frames/sec in
IMX533 backlit sensor
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.
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.
Low read-out noise, high dynamic range. 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.
Zero Amp Glow
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
DDR Memory Buffer
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.
Note: We recommend using an external 12V power supply to power the camera instead of USB 3.0/2.0 only
Note2: We recommend using a 1,25" IRUVcut filter. It fits into the 1,25"-T2 connector, placed inside the 11mm T2 ring that comes with the camera
