Compact, Cooled SWIR Camera
Balluff has developed the most compact cooled SWIR camera in the world. The sensor is cooled by a Peltier element, and the generated heat is transferred directly to the housing.
Balluff is setting a new standard with its new cooled SWIR sensors, available in resolutions ranging from 1.3 to 5.3 MP. A cooled SWIR sensor is housed in a compact 40 x 40 x 77.4 mm enclosure—completely fanless. At the heart of this development is optimized heat transfer from the electronics to the housing, allowing the generated heat to be quickly dissipated into the environment.
A precisely fitting heat sink, developed specifically for the SWIR cameras, is mounted on the camera and dissipates heat where it is generated. A key advantage is the compact, precision-fit design: The cooling plate can be mounted above or below the camera, requires virtually no additional installation space, and allows for the integration of additional mounting plates. This makes the system ideal for tight installation situations.
The result is a space-saving, closed cooling circuit without disruptive air turbulence—ideal for sensitive applications. With a sensor cooled to below 15°C, the cooling plate can dissipate so much heat that the camera itself is only about 10°C warmer than the ambient temperature of 20°C. The compact cooling plate cools both the sensor and the processor simultaneously—either via air or water—and operates completely fanless. This eliminates air currents and potential fan failures, ensuring the camera remains reliable over the long term. Should the cooling system malfunction, the camera automatically shuts down at 70°C for self-protection.
