Optikos Corp. has announced Finite Conjugate and Afocal Testing module options and enhanced software support for its OpTest Lens Testing System.

Afocal module AF-1100 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. The AF-1100 includes 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 lens and external aperture stop are 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 to minimize 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 noninverting afocal lens measurements.

Finite Conjugate Platform module FP-1100 for OpTest benches enables the evaluation of lenses at finite object distances such as microscope objectives, macro lenses or other lenses designed to focus on near objects. The FP-1100 automates the translation of the OG-1000 Object Generator, perpendicular to the optical axis to establish height, and allows the object distance to be set through the translation of the platform along the axis. Both axes feature a linear position encoder, and the Z-axis reading may be summed in OpTest 7 software with that from the LP-1000 image analyzer axis in order to create a seamless Z-axis for the bench.
