Compass™ 2 – Metrology Systems | Zygo

Features and Benefits:

There are two models of Compass 2 systems available, depending on your metrology needs

Compass 2 – ZYGO’s advanced solution for precision metrology of micro lens surface form, deviation from prescription, and relational/dimensional parameters. This is the ideal choice for applications that require the analysis of rotationally symmetric spherical and aspheric, geometrically truncated, and freeform surfaces.

Compass RT – A fast and flexible system for precision metrology of micro lens relational/dimensional parameters, plus general profilometry applications. This is the ideal choice when form deviation metrology is not required.
