Abstract
Methods, apparatus and systems for testing an optical element are described. One example device for measuring a test optical component includes a pre-conditioning optical module positioned to receive an optical beam from a light source and to produce a beam having a non-collimated beam profile or a freeform wavefront. The device further includes a beam splitter positioned to receive the beam output from the pre-conditioning optical module and to direct a first portion of the beam to a reference arm configured to accommodate a reference optical component, and to direct a second portion of the beam to a test arm configured to accommodate the test optical component. The device also includes a beam combiner positioned to receive the beams from the reference arm and the test arm after reflection or refraction by the reference and the test optical components.
