Soooo I started taking excellent photos…. and was about to label and upload photos and films I took through my polarizing microscope, when I realised I needed scale! Rule #1!
So, I gave up on the maths – the slight zoom in my camera ruled out that – and invested in an “Advanced Calibration Slide”, which arrived yesterday.
It has five calibration patterns.
0.07mm, 0.15mm, 0.6mm and 1.5mm calibration dots.
X-Y calibration scale (In the circle in the picture of the slide above) with a smaller division of 0.01mm. The scale is 1mm long in both X and Y direction and is first divided into 0.1mm and them 0.01mm. At the centre, it has a 0.04mm square divided by 5 lines in both X and Y direction and providing much more choice for calibration.
Now let the fun begin on a
large small scale!
