What it is

General reference — not yet source-verified

Optical metrology systems in this class are used to inspect and quantify the shape or figure of optical surfaces without contact. Precision optics instruments of this kind are typically used in laboratories, optics production, and inspection settings where surface form and related optical quality must be checked.

How it works

The Wyko 400S provides live fringe output and phase shifting capability. The Wyko 400S uses a simple twin spot alignment system. The Wyko 400S supports operation with wavelength sources of 633 nm or 1.06 µm.^[2]

Where it fits in the process flow

General reference — not yet source-verified

Precision optics inspection tools in this class are generally used after fabrication or finishing steps that create the final optical surface. Precision optics inspection tools in this class commonly sit around grinding, polishing, figuring, coating verification, and final quality assessment loops. Measurements from tools in this class are commonly used to decide whether an optic proceeds to further correction, cleaning, assembly, or acceptance.

Applications

The Wyko 400S is used for evaluation of a wide range of optics.^[2]
