High Efficiency Low Scatter Echelle Grating, Phase I

Completed Technology Project

Project Description

High Efficiency Low Scatter Echelle Grating, Phase I
A high efficiency low scatter echelle grating will be developed using a novel technique of multiple diamond shaving cuts. The grating will have mirror surfaces on both faces for high efficiency in high orders. The grating will be manufactured using a 3/4 ton air bearing grating carriage that oscillates at 30 strokes per minute between two non-contact magnetic fields. The groove spacing will be controlled by an interferometer measuring system and feedback system between the optical blank and diamond cutting tool. More »
