Sony IMX571 Sensitivity

The sensor G Sensitivity of ATR2600M is 484.6 mv with 1/30s. The sensitivity is measured with a testing standard lens with CM500S (t = 1.0 mm) as an IR cut filter and image at F8.0. If the image is measured at F5.6, the result could have been 2 times of the current value. Its spectral sensitivity is shown in Figure 2

16bit ADC and ROI

ATR2600M has built-in 16-bit ADC. It also has 12-bit output mode for hardware binning and a smaller resolution. The camera also supports hardware ROI, and the smaller the ROI size is, the higher the frame rate is.

Table 2 shows the frame rate of ATR2600M in 1 6 8 b it mode, USB3.0 USB2.0 data transfer interface at different resolutions:

Table 2 ATR2600M Frame Rate at Different Resolution/Data Bit/Data Transfer (USB3.0/ USB2.0)

DDR3 Buffer

The ATR2600M camera has a 512 MB ( DDR3 buffer, which helps maintain the stability of data transmission, and effectively reduces the amp glow caused because image data can be temporarily buffered without being sent hastily to the receiver.

Binning

ATR2600M supports digital binning from 11 to 88 in either the stacking or averaging method and hardware binning from 1 1 to 3 3 in the averaging method. Hardware pixel binning is much faster than software binning.

Conversion Gain Switch

ATR2600M supports HCG and LCG mode switches, the Gain ratio is 3.0 1

Power and Cooling System for Precise Temperature Regulation

Please remember, that the Camera can be powered only by a DC12V 3A power source. The cooling system of ATR2600M is two-stage Thermoelectric Cooling (TEC) with controllable electric fan assisting heat dissipation. The TEC system is controlled by the PID algorithm, which allows the TEC to be precisely regulated towards the target temperature with 0.1  C deviation The working temperature can be regulated to a specific number, and the effective temperature drop can be 4 2  C from the ambient temperature. Such an efficient cooling system guarantees the stability of ultra-low noise mode and the quality of the camera image.

Zero Amp-Glow

ATR2600M 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 ATR2600M shows zero amp glow.

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 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: 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. The 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.

For the ATR series camera, the Gain Value is in xxx% mode. Here xxx is used as the x-axis ( Gain Value ) for the description of the camera performance

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. It is impressive that ATR2600M comes with Low Noise Mode, which means users can get even lower readout noise by selecting Low Noise Mode while the frame rate is reduced as a sacrifice. Its significantly low read noise is 0.77 2.77 e Low Noise Mode ).

All following data were acquired in SharpCap with ASCOM driver:

(The ASCOM Driver version for camera TEST in Low noise mode & High full well mode was relatively new)

Camera Mechanical Connection with Adapter

ATR2600M can be connected to a telescope with a 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. ATR2600M comes with an M42x0.75 mount and can connect to the telescope with the M42x0.75 thread in a direct way. ATR2600M can also connect to the telescope that use 1.25” or 2” eyepieces by M42M 1.25” or M42M 2” adapter. Figure 12 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 10 list the details of the camera and adapter parameters.

Camera Electric Connection with Accessories

On the back side of ATR2600M , 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 IMX571, ATR2600M (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 a 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.
