OCAM2K and OCAM2S are high speed low noise EMCCD cameras able to run at 2067 fps (3700 fps in binning) with subelectron readout noise.
To achieve this performance, OCAM2K integrates the Teledyne E2V CCD220 sensor, a Peltier-cooled 240 x 240 pixel frame-transfer 8- output back-illuminated sensor. Whereas, OCAM2S features an integrated electronic shutter and uses the Teledyne E2V CCD 219 Peltier-cooled 240 x 240 pixel 8 output split frame transfer CCD.
The Embedded Electronic Shutter in OCAM2S is able to deliver an arbitrary number of integration pulses that can be shorter than 1 μs with a precision better than 50 ns.
To minimize smearing, the CCD220 and CCD219 high speed metal buttressed clock lines are driven by OCAM2K and OCAM2S at a speed as high as 7 Mlines/s transferring each frame in the store section in only 12 microseconds. OCAM2K and OCAM2S also offers an extremely low latency: 43 μs between exposure and first pixel availability.
Developed by astronomers for astronomers for visible imaging, with up to 95% quantum efficiency over a wide spectrum (from 400 to 900 nm), the EMCCD cameras OCAM2K and OCAM2S are the fastest visible cameras with subelectron read out noise. For wavefront sensing applications, OCAM2K and OCAM2S can be equipped with a 20 x 20 subapertures microlens array (customizable on request).
