Sony IMX571 Sensitivity

 

The sensor G Sensitivity of ATR3CMOS26000KMA is 871 mv with 1/30s. Die Empfindlichkeit wird mit einem Teststandardobjektiv mit CM500S (t = 1,0 mm) als IR-Sperrfilter und einem Bild bei F8,0 gemessen. 

 

 

 

16bit ADC und ROI

 

The ATR3CMOS26000KPA has built in 16bit ADC. It also has 12bit 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

ATR3CMOS26000KMA 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 ATR3CMOS26000KMA supports digital binning from 11 to 88 in either stacking or averaging method, and hardware binning from 11 to 33 in averaging method. Hardware pixel binning is much faster than software binning.

 

Conversion Gain Switch

ATR3CMOS26000KMA support HCG and LCG mode switch, the Gain ratio is 3.01.

Zero Amp-Glow

ATR3CMOS26000KMA 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 ATR3CMOS26000KPA shows zero amp-glow.

Camera Mechanical Connection with Adapter

The ATR3CMOS26000KMA 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 ATR3CMOS26000KMA comes with M42x0.75 mount and can connect to telescope with the M42x0.75 thread in a direct way.

The ATR3CMOS26000KMA can also connect to the telescope who use 1.25” or 2” eyepieces by M42M-1.25” or M42M- 2” adapter. Figure 10 shows the connection of the camera and the adapter. After the adapter is screwed to the camera, the camera can insert into the telescope’s eyepiece tube. Table 8 list the details of the camera and adapter parameters.

Camera Electric Connection with Accessories

 

On the back side of ATR3CMOS26000KMA, there are 3 connection ports: DC 12V/3A power port, USB3.0/ USB2.0 port and USB-HUB.

Due to the significantly larger power cunsumption of IMX571, ATR3CMOS26000KMA (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.
