INTERFERENCE LIGHT FILTER WITH ADJUSTABLE BAND PASS

摘要

FIELD: physics. ^ SUBSTANCE: interference light filter has a Fabry-Perot resonator in form of two plates with mirror coatings placed with a gap between them on holders of a mechanism for moving the plates. Between the mirror coating and the plate there is a compensation layer whose thickness varies in accordance with a law which provides equivalent arrangement of the mirror coatings relative each other. ^ EFFECT: simple design due to exclusion of an adjustment device and easier manufacturing due to simplification of requirements for the plane of the plates and exclusion of the adjustment process. ^ 1 dwg
