ToupTek ATR3CMOS09000KMA (IMX533) - Mono 

HOT NEW!

The ATR3CMOS09000KMA is finally the mono version of the IMX533 colour sensor used in the ATR3CMOS09000KPA and ZWO AIS 533 MC PRO.
The advantages of the IMX533 are now also available as a high-resolution mono version in the easy-to-handle 1" square sensor. This makes even the RASA8 fun. 




The ATR3CMOS09000KMA camera is designed specifically for astrophotography. It is mainly used for deep sky photo shooting, since the camera has cooled CMOS sensor, ultra-low readout noise and zero amp-glow. It can be also used for planetary photo shooting. Its extraordinary performance and extensive usage will give you great astrophotography experience.

Professional deep-sky astrophotography: The sensor is perfectly suited for extended nebulae, star fields or the lunar surface. It has an area of 11.31mm x 11.28mm and is easy to use with all telescopes. No more night-long jutting, as with the combination of RASA and IMX-571 sensor (APS-C).

Thermoelectric cooling: The Peltier cooling system reduces image noise. Noise caused by dark current has almost completely disappeared at up to 35°C below ambient temperature. In addition, the exact control of the sensor temperature is very helpful for calibrating the astrophotos with dark frames: they can all be taken at the correct temperature. The low-noise images show more details and require less post-processing.

USB hub: Via two additional USB 2.0 ports on the back of the camera, additional devices (for example a guiding camera) can easily be connected to this hub. An additional cable connection from your PC to each individual device is therefore not necessary.

Connection: The camera can be adapted to almost any telescope - with an M54x0.75(f) thread and the back focus of 17.5 mm. M48x0.75(f) adapters and an extension for the usual 55mm backfocus are also included. A T2 adapter ring completes the connection options. The 2" outer diameter of the adapters allows of course a telescope connection like any standard 2" eyepiece.

The supplied robust case is filled with foam. Thus the camera is very well protected during any transport. If the camera should ever be separated from the telescope again.

Transmission: A filter protects the sensor chamber from dust and moisture. The Topuptek colour CMOS cameras are equipped with an infrared blocking filter. CMOS sensors are also sensitive to incident infrared light, making correct colour reproduction impossible. In contrast, Topuptek mono CMOS cameras have an anit-reflective protective glass that transmits ultraviolet and infrared light in addition to visible light. This allows complete control over the transmission curve through the use of additional filters - a prerequisite for advanced photographic or photometric applications.

Practical camera software: The downloadable ToupSky software enables uncomplicated and comprehensive camera control. ToupSky allows full control over all essential parameters - without an overburdening interface. The software is compatible with Windows 8/10/11.

Compatibility: Touptek cameras can be controlled by a wide range of recording software via the common ASCOM and INDI interfaces as well as AStro Dshow drivers. Native compatibility with a growing number is available with popular programs such as PHD2 and N.I.N.A.

Specifications

Sony IMX533 Sensitivity

The sensor G sensitivity of ATR3CMOS09000KMA 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 ATR3CMOS09000KMA has built in 14 bit 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

ATR3CMOS09000KMA 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 ATR3CMOS09000KMA 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

ATR3CMOS09000KMA 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

ATR3CMOS09000KMA 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 ATR3CMOS09000KMA shows zero amp-glow.

Camera Mechanical Connection with Adapter

The ATR3CMOS09000KMA 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 ATR3CMOS09000KMA comes with M42x0.75 mount and can connect to telescope with the M42x0.75 thread in a direct way. 

The ATR3CMOS09000KMA 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 ATR3CMOS09000KMA, 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, ATR3CMOS09000KMA (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.
