Our brand new cooled version of ASI178MM Monochrome Camera allows the sensor to be cooled to 35C to 40C degrees below ambient!
Here is a 60s long exposure dark file of this Camera. Back-illuminated CMOS Image Sensor with 14bit ADC.
ASI178MM has a 1/1.8″ and 6.4M pixels sensor IMX178 with SONY STARVIS and Exmor R Technology.
Extremely low read noise(2.2 e) , high sensitivity and 14bit ADC make it very suitable for astronomy and microscopy high resolution photograph.
The QE peak value is more than 81%.

Reliable Mechanical Structure
There are four screws that seal the sensor chamber. Our camera design has been extensively tested and is very stable.
Even when used in higher humidity environments, ASI178-Cool will still works fine without dew problems.
USB 3.0 Port & USB2.0 HUB
USB 3.0 Port: Provides 5Gb bandwidth to make it possible for ASI178-Cool to run at 30 fps (14bit, normal mode) or 60 fps (10bit, high speed mode) at full resolution (6.4Mega).
USB 2.0 HUB: Can connect with various accessories, including a filter wheel, guide camera or electronic focuser, allowing you to manage your cables better. There are two short 0.5m USB2.0 cables included with the ASI178-Cool. The hub is powered by the external power supply if you connect one.
ASI178MM-Cool has 2 stage TEC cooling system to enable very deep cooling (35°C-40°C below ambient). The cooler requires an external power supply, which is not included with the camera. You may order a suitable power supply from here.
We recommend using a 12V/3-5A or more DC adapter for cooler power supply (2.1×5.5, center positive).
Using a battery with 9-15V is also suitable for the cooler power supply.
