Application Notes

The Michelson Interferometer Experimental Setup

Albert A. Michelson won the 1907 Nobel Prize in Physics “for his optical precision instruments and the spectroscopic and metrological investigations carried out with their aid.” One …

Application Notes

Phase-Shifting Interferometry for Determining Optical Surface Quality

Determining the surface quality of a critical component—the deviation from the intended shape whether flat, spherical, etc.—is crucial to high-precision manufacturing. Traditional methods …

Videos

Picomotor demo using interferometer

A demonstration of the New Focus Picomotor using an interferometer. The Picomotor allows for accurate, minute adjustments that cannot be achieved using a manual micrometer.

Application Notes

Testing MEMS-based Accelerometers in GPS Navigation System with a Custom 2-Axis Gimbal

Built from two, high-precision RV series rotary stages, the inner stage providing roll motion and the outer stage assembly providing elevation, the gimbal is an ideal platform to test …

Application Notes

Theory of Lloyd’s Mirror Interferometer

There are two principal methods for producing coherent sources for interferometry. One uses the division of wavefront, as in the Young’s double slit experiment. The second divides the …

Technical Notes

Interfacing an Interferometer Encoder to an XPS Controller

This tech note describes how to configure and setup a Renishaw Interferometer Encoder with an XPS controller. This can help with both diagnostics and measurement for an enhanced level …

Videos

Interferometric Testing Wavefront Distortion

Actual (not simulated) interferometric testing of our LWD Mirror Mounts demonstrate that the low-stress mirror mounting clamp significantly reduces wave front distortion. In this video, …
