There are several methods. One of these methods is to draw a cross line on the monitor and measure it by using digital micrometer XY table.


Another methos is to measure the length by using software. In that case, the lens, camera, PC monitor and resolution are all set on the same environment

Therefore, if you calibrate at each magnification and save the calibration data first. Then, you can view the data without calibrating.

Since our standard variable magnification lens (SDS – M) has the stop key, it is reproducible for anyone using it. It is possible to measure if you already read the calibrated file with that scale before.
