METHOD OF COMPENSATING FOR LIGHT LOSSES CAUSED BY SPHERICAL ABERRATIONS IN SYSTEM WITH FABRY-PEROT INTERFEROMETER

摘要

FIELD: physics.SUBSTANCE: cylindrical lenses provide a section of a pre-collimated beam at the input mirror of a Fabry-Perot interferometer, equal to the diameter of the effective region of the interferometer. A minimum beam section is provided between the mirrors at a distance half the length of the interferometer.EFFECT: compensating for light losses caused by spherical aberrations in a system with a Fabry-Perot interferometer.11 dwg
