Plano Transmitted Wavefront

• Wavefront transmission setup

This setup is used to measure distortion of a plane wave transmitted through the article under test. It is typically used for windows, filters, and prisms. In addition, glass and other transparent raw material may be examined for homogeneity evaluation. Since the measurement beam passes through the article under test this article need only be placed nominally perpendicular to the optical axis of the test beam. No special mount or alignment is required.

Suggested Accessories: Phase Shifting Interferometer, Transmission flat, 4%; Mount, 2-axis (tip-tilt); Reference flat, 4%.
