Multi Polish Robot Polishing Method
This invention is for a robotic system that is designed to polish multiple regions of a large optical surface simultaneously. It includes a novel internal propulsion mechanism that uses coils to drive a magnetic weight along a circular track. This method can accelerate the mirror fabrication time, eliminating the need for off-line testing, reducing...

3D Printing Mirror (Radial Lithography Surface Figuring)
The technology enables less expensive fabrication of mirrors without compromising quality. This is done with a 3D printing technique that uses lasers and a rotating platform to craft the desired shape of the mirror. The new method can print mirrors that can be used in large-aperture telescope applications such as space telescopes. It can also fabricate...

Pawlowski-Choi Imaging Spectrometer
This imaging spectrometer is a compact device designed to analyze light and determine its spectrum. While it is similar to the Czerny-Turner spectrometer design, it features notable differences that enhance its functionality. The spectrometer uses two spherical mirrors to direct and focus the light and incorporates a Littrow prism in a unique, non-traditional...

Pseudo-Nulling Mach-Zehnder Metrology
This technology is a novel Mach-Zehnder interferometer that uses a a pseudo-nulling configuration with a converging beam, to test two optical components against each other, rather that testing one optical component against a reference component
Background:
As the capability of optical manufacturing has grown such that it is easy to mass produce...
