Match your focal length to the R-Flex system

A variety of standard objectives are available for the R-Flex systems. Your focal length is not yet available? We are able to customize an objective exactly to your need.

Because different users have different needs, the f/# of HASO R-Flex can be adapted to each user’s requirements by choosing the focusing module best suited for the task at hand. As the sample f/# defines the best focusing module, Imagine Optic offers factory models that are available from f/#=1 to f/#=16 to ensure maximum resolution, whereas custom models for special needs can equally be delivered. Please see the product page of standard focusing units.

(1) should be divided by 2 if the optical system under test is characterized by double-pass method
(2)  focal length of the module
(3)  WFE is the wavefront error at the output of the module for the largest included round pupil.
(4) distance between the focalization point and the first optics (alignement holes must be removed)
(5) YES means that the microlenses are imaged at infinity by the module.
(6) These modules consist of the association of a x3 beam expander and MOD50-1VIS or MOD50-2 VIS.
