Abstract

Deposition sources deposit material onto mirrors used in ring laser gyros. The mirrors are placed in a rotating apparatus called a planet which rotates above the deposition sources which emit the material upwards. This operation will result alternating, multiple layers of the differing materials deposited onto the mirror. A barrier placed between the deposition sources prevents material from being deposited at high angles which increases the efficiency and ideal operability of the mirrors in the ring laser gyro.
