Photonfocus has introduced the A1312 series of CMOS sensors. The sensors are designed and fabricated in a 0.35µm CMOS technology optimised for outstanding sensitivity and quantum efficiency. The resolution is 1312 x 1082 pixels, with 8 x 8µm square pixels and over 60 per cent fill factor with excellent image quality. The fastest version of the sensor delivers 110fps at full resolution.
All monochrome versions of the new A1312 CMOS sensor provide a high dynamic range of up to 120dB with LinLog technology. The fast global shutter ensures sharp and smear free images at high frame rates.
The ROI (Region of Interest) can be freely set in the sensor, which supports multiple ROI as well. The speed of the sensors can be increased to thousands of frames per second by reducing the ROI through horizontal and vertical windowing.
The A1312 sensors are able to begin capturing a fresh image while outputting the current image, thus maximising the available exposure time and frame rate.
The monochrome versions are supplied without cover glass, which reduces the number of elements in the optical path, maximises sensitivity and avoids internal reflections and associated image artefacts.
The sensors have an extended spectral range covering 350nm to 1000nm. A tough inorganic anti-reflective coating significantly reduces the amount of light reflected back from the sensor surface, increasing sensitivity and avoiding unwanted artefacts created by reflections in the system optics, especially in the near infrared range of around 850nm.
