Aperture Dimensions 7.4mm x 5.4mm (39.96mm2)

Four Pixel Aperture Mask

The holes in the aperture mask align with the centre of the device pixels, creating four illumination areas of 39.96mm2. There is a border of 0.6mm between the edge of the aperture and the edge of the pixel. This helps to reduce edge effects during device characterisation.
