Camera Sensor

Diagonal 8.35 mm (Type 1/2) Approx. 2.13M-Effective Pixel Color CMOS Image Sensor.



CMOS Image Sensor for Industrial Applications that Realizes High Sensitivity Approximately Twice That of the Existing Product

Sony Semiconductor Solutions Corporation has developed the CMOS image sensor “IMX385LQR” for industrial applications. This new image sensor realizes high sensitivity approximately twice that of the existing product (IMX185LQJ)*1.
The IMX385LQR pursues picture quality at low illuminance most needed by cameras for industrial applications and mounts pixels with a sensitivity of 2350 mV, which is the highest sensitivity among Sony image sensors for industrial applications*2. In addition, SNR1s of 0.13 lx*3, which is the highest performance among Sony Full HD-compatible image sensors for industrial applications, is achieved by mounting an internal programmable gain amplifier and high conversion gain pixels. Superior performance as an image sensor for industrial applications is further achieved by combining HDR (High Dynamic Range) technology with technology that improves sensitivity in the near-infrared light region.

 Astrophotography Performance

ASI385MC-Cool offers very good performance for astrophotography. Low read noise, high dynamic range, QE peak >80%, AR protective window and much more.


Dark Current

ASI385MC-Cool has extremely low dark current, you can click here to see dark frame of ASI385 camera(HDR settings, 60s, -10°C).

USB 3.0 Port & USB2.0 HUB

USB 3.0 Port: can provide 5Gb bandwidth to let ASI385 run at 67 fps (12bit, normal mode) or 120 fps (10bit, high speed mode)  at full resolution(2.13Mega).

USB 2.0 HUB: can connect with various accessories, such as filter wheel, guide camera and electronic focuser, so you can manage your cable better with USB2.0 hub. There are 2 short 0.5m USB2.0 cable come with ASI385MC-Cool. the power of hub source from external power supply if you connect it.

Cooling System

ASI385MC-Cool has 2 stage TEC cooling system to enable very deep cooling (40°C-45°C below ambient). you need external power supply to power on the cooler. AC-DC power adapter is not included in this package, you can order from here.

We recommends 12V at 3A~5A or more DC adapter for cooler power supply(2.1*5.5, center positive).

Battery from 9-15V is also suitable for cooling power supply.

    It I need It , shall I use 1,25’ or 2’ variant ?


    • Sean Wang


      this camera use AR coating, so you can put a 1.25″ IR-cut in front of the camera.

  4. :

    1)but can you please check the extra cost and tell me later on(about in 2-3 weeks)?
    2)i have a 6” f5 telescope so what can i capture with this camera and the telescope?
    3)to attach the camera to the telescope we need to screw 11mm t2 extender. does it come along with the camera or i have to
    buy it. can we directly join the 1.25” t mount to the extender?




    • Sean Wang


      Hi, Shubham. I can’t tell extra cost, usually won’t be much. You can do both planetary imaging and DSO imaging.
      11mm T2 extender is on camera, it is removable, also you can directly use 1.25 T-mount for imaging.


  5. :

    I live in india and i want to buy asi385mc-cool color camera. What will be the total cost of this camera including all the types of taxes,shipping charges,and other additional charges? is the shipping free? which things i can capture from a light and air polluted city.
