Rosel holding has delivered the first batch of the UTK-1 general-purpose highly sensitive TV cameras to the customer. UTK-1 TV cameras can “see” in low light conditions and operate in extreme conditions, including the Arctic region. They can be used in computer vision systems and research equipment. 

The new products are included in a general-purpose TV camera line made by Central Research and Development Institute ‘Electron’ (included in Rosel) and used in various electromagnetic ranges, from ultraviolet to near-infrared short-wave range.

The UTK-1 has a highly sensitive backside illuminated large-pixel matrix. This configuration allows light to pass through a substrate, rather than electrodes, therefore the sensor captures more light. Large pixels also collect more light. Eventually, the matrix provides better sensitivity, high resolution and minimized noise. 

The matrix itself is placed in a single metal-ceramic housing with an input window and thermoelectric cooler. A sealed space is provided in the device for better cooling and is later filled with xenon. This design allows the sensor to be cooled with a temperature drop of 40 °С from the heat removal temperature.
