TEMStrain    

Camera length

Camera length must  be specified for each pattern by clicking on “Settings” command button and by selecting “Microscope settings” tab. The units of camera length must be the same as the units of pixel size. It is recommended to use [mm]. The values of camera length corresponding to different patterns of the same set may be different. 

The value of camera length can be also modified by (right or left) clicking on the “C.L.” command button in the “Fine-tuning”  frame box in the main (TEMStrain) window of the program.
