OCAM2S is a high speed low noise camera with an integrated electronic shutter able to run at 2067 fps with subelectron readout noise. To achieve this performance, OCAM2S uses the E2V CCD 219 EMCCD, an 8 output split frame transfer CCD. To minimize smearing, the CCD219 high speed metal buttressed clock lines are driven by OCAM2S at a speed as high as 7 Mlines/s transfering each frame in the store section in only 12 microseconds.
The Embedded Electronic Shutter in OCAM2S is able to deliver an arbitrary number of integration pulses that can be shorter than 1μs with a precision better than 50ns. Contact us for more details.
OCAM2S also offers an extremely low latency: 43μs between exposure and first pixel availability.

OCAM2S-WFS is a high speed low noise Shack-Hartmann Wavefront Sensor able to run at 2067 fps with sub-electron readout noise. To achieve this performance, OCAM2S-WFS uses the E2V Technologies CCD219 EMCCD, which is an 8 outputs split frame transfer CCD.
To minimize smearing, the CCD219 high speed metal buttressed clock lines are driven by OCAM2S-WFS at a speed ashigh as 7 Mlines/s transfering each frame in the store section in only 12 microseconds.
The Wavefront Sensor is provided in standard with 40×40 or 20×20 Micro-lenses array (fused silica, AR coating). Specific μLenses array can be fitted. Custom design is available upon request. Contact us for more details.
