=== Calculating Camera Resolution ===

An Ipad with 52ppcm (pixel per cm) was used to calculate the camera resolution. This means that one pixel is 10/52 mm wide, that is roughly 0,2 mm. These 0,2 mm equal 300 pixels of the camera image. Therefore one pixel of our camera shows 0,00067 mm (0,2mm/300) of the specimen.

Therefore one pixel of our camera shows 0,00067 mm (0,2mm/300) of the specimen. Knowing that the image is 640 pixels wide and 480 pixels high, the image size adds up to 0,43 mm in width (0,00067*640) and 0,32 mm in height (0,00067*480).
