Dual Gain Monochrome CCD Camera

The Cohu 2740-Series provides near Gen-1 low light level performance at a fraction of the price. By using specially designed dual-gain circuitry this professional grade camera is a cost-competitive solution for industrial inspection, machine vision, security, and medical imaging.

For conventional installations, its compact size and single connector wiring make it easy to put nearly anywhere. For specialized installations, the front plate is easily removed and oriented up to 45° (180° optional) off center, adding to its mounting options. When used for outdoor surveillance, the camera and related hardware can be enclosed in a Cohu sealed and pressurized housing. Optics are standard C/CS-mount

Built to take it.

The 2740Series can be accelerated and vibrated under rigorous conditions while maintaining a clear, stable image, day in and day out. For the harsh outdoors, Cohu includes a sealed and pressured version of the camera in this product line. Cohu has more than 40 years experience building cameras to military specifications and we apply that real-world knowledge to our products.
