Specifications

Sony IMX533 Sensitivity

The sensor G sensitivity of ATR3CMOS09000KPA is 535 mv with 1/30s . Sensitivity is measured using a test standard lens with CM500S (t = 1.0 mm) as IR cut filter and an image at F8.0. 

14bit ADC und ROI

The ATR3CMOS09000KPA has built in 14 bit ADC. It also has 8bit output mode for hardware binning and smaller resolution. The camera also supports hardware ROI, and the smaller the ROI size is, the higher the frame rate is.

DD3 Buffer

ATR3CMOS09000KPA camera has a 512MB (4Gb) DDR3 buffer, which helps maintain the stability of data transmission, and effectively reduce the amp-glow caused because image data can be temporarily buffered without being sent hastily to the receiver.

Binning

The ATR3CMOS09000KPA supports digital binning from 1x1 to 8x8 in either stacking or averaging method, and hardware binning from 1x1 to 3x3 in averaging method. Hardware pixel binning is much faster than software binning.

Conversion Gain Switch

ATR3CMOS09000KPA support HCG and LCG mode switch, the Gain ratio is 3.05.

Camera Performance Analysis 

Camera performance can be evaluated with e-/ADU, Read Noise, Full Well and Dynamic Range. 

e-/ADU: The sensors found in cameras used for vision applications have pixels that convert incoming photons into electrons. Gain on a CCD /CMOS camera represents the conversion factor from electrons (e-) into digital counts, or Analog- Digital Units (ADUs). Gain is expressed as the number of electrons that get converted into a digital number, or electrons per ADU (e-/ADU). 

Read Noise: Read Noise is the most important reference to measure the performance of a camera. Lower read noise usually means better SNR and better quality of image. Read Noise is created within the camera electronics during the readout process as the electrons are subjected to the analog to digital conversion, amplification and processing steps that enable an image to be produced. 

Full Well: The electrons are held in each pixel and are converted into electrical charge which can be measured to show the amount of light that has fallen on each pixel. The maximum electrical charge possible is termed "full well capacity". Under the same conditions such as noise and A/D converter quality, the greater full well capacity a sensor has, the wider dynamic range the sensor has. As there is a limit to the depth to which pixels can be made, the full well capacity is often proportional to the frontal area of the light gathering element of the pixel. 

Dynamic Range is the ratio between the maximum output signal level and the noise floor at minimum signal amplification (noise floor which is the RMS (root mean square) noise level in a black image). The noise floor of the camera contains sensor readout noise, camera processing noise and the dark current shot noise. Dynamic range represents the camera’s ability to display/reproduce the brightest and darkest portions of the image and how many variations in between. This is technically intra-scene dynamic range. Within one image there may be a portion that is in complete black and a portion that is completely saturated.

Zero Amp-Glow

ATR3CMOS09000KPA has been carefully designed and is able to achieve zero amp-glow photo shooting. Figure 3 and Figure 4 show the different cameras at 20°C and 5-minute exposure time with and without amp-glow. By comparison, the image captured by ATR3CMOS09000KPA shows zero amp-glow.

Camera Mechanical Connection with Adapter

The ATR3CMOS09000KPA can be connected to a telescope with proper adapter, or the camera lens. The most common adapters are already included in the package, but we also provide some specific adaptors based on the requirement. 

The female flange to the sensor is 17.5mm. The ATR3CMOS09000KPA comes with M42x0.75 mount and can connect to telescope with the M42x0.75 thread in a direct way. 

The ATR3CMOS09000KPA can also connect to the telescope who use 1.25” or 2” eyepieces by M42M-1.25” or M42M- 2” adapter.

Camera Electric Connection with Accessories

On the back side of ATR3CMOS09000KPA, there are 3 connection ports: DC 12V/3A power port, USB3.0/ USB2.0 port and USB-HUB. 

Due to the significantly larger power consumption of IMX533, ATR3CMOS09000KPA (including the cooling system) is now booted up only by 12V/3A power supply. USB3.0 no longer workds as a power source but only as a data communication method. The USB-HUB provides connection with other devices, which allows user to avoid the mess of cable management. Once another device is connected through the USB-HUB, it will be connected to PC device through the USB3.0/USB2.0 port.
