I've tried to measure the cmos sensor under the microscope and it is roughly 2mm in the longest dimension (the one I'm using), will need to calibrate it with known shims to calculate um / pixel but using this rough measurement it is 2/640 = 0.003mm. The scale in the picture is 0.1mm per division.

Also important to note that as you're using a fitted profile you're able to give a measurement to a higher level of precision than that.

Que the mandatory accuracy vs precision debate...
