Measuring Magnification

When testing a lens at finite conjugates, the EFL wizard provides a convenient way to measure magnification.

The actual procedure is the same as described in the section on measuring EFL.

Information specific to measuring magnification

The Optical Layout window must be set up for finite conjugates, as shown below.

When the Optical Layout is set up for finite conjugates the EFL wizard will display magnification automatically.

When the Optical Layout is set up for finite conjugates it is not possible to use the EFL wizard to measure focal length.
