Optiscope SA look like a conventional camera but includes all the hardware needed for temporal and luminance measurements. An imaging objective collects the light in a angular aperture of ±1° following VESA standard. An image of the target is obtained with a color CMOS sensor. Part of the light goes on a photomultiplier across a photo peak filter. An additional system including calibrated photodiode and LED illumination allows self calibration for accurate luminance measurements. The Optiscope SA can be used at various distances from the display down to ~30cm.

The electronics includes a 16bits analog to digital converter and on board 4M memory. USB 2.0 connection with PC allows real time and unlimited acquisitions with a sampling step between 5 and 20µs. The CMOS color sensor offers a 1M pixels resolution for alignment purpose.Dark noise is automatically corrected using a shutter.
