The new AF-1100 Afocal Module is an accessory to the LP-1000 Lens Platform that provides the second rotation required when measuring afocal lens assemblies such as visual riflescopes and telescopes. Features include:
- A length of linear rail with a carrier for mounting the lens under test and placing the exit pupil over the axis of rotation.
- A fixed decollimating (eye) lens and external aperture stop made coincident with the plane of the exit pupil.
- The separation between the two rotary axes is set to the distance reported in OpTest 7 software–minimizing the pupil walk across the collimated beam over the full field of view.
- The AF-1100 and OpTest 7 software fully support both inverting and non-inverting afocal lens measurements.
