The invention refers to a chuck pallet () with solid groove-sidewalls () for clamping chucks (), whereby the x-y-references () of the chuck pallet () are allocated in the same plane () as the z-references () and the x-y-references () are also allocated at the solid groove-sidewalls (). The solid groove-sidewalls () have thereby a tapered profile.

Solid pallet for clamping chucks

A chucking fixture for a tool or a workpiece, comprising a chuck and a toolholder or workholder matching the chuck, wherein the chuck has posts having bearing surfaces for orienting the tool or workpiece in an X and Y direction and having end faces for establishing a plane perpendicular to the Z direction, wherein devices for measuring the distance between the chuck and the toolholder or workholder are formed in the bearing surfaces and in the end faces.

The invention provides a method and system for measuring the length of a reflective resonator, by analyzing an electromagnetic spectrum emitted therefrom. The emitted spectrum is used for estimating a first cavity length. This estimation is thereafter improved, by first computing at least one interference number for the spectrum, adjust this value to e.g. an integer or half-integer depending on the configuration of the resonator, and thereafter re-calculating the length of the resonator using the adjusted value of the interference number. The above is an efficient way of improving the accuracy in the determination of a physical property of a resonator.
