Optical cavity lenses
WebThe cavity is defined by two mirrors. One is partially reflecting and allows the output beam to escape. The simplest cavity is defined by two mirrors facing each other — a total reflector and a partial reflector whose reflectance can vary between 30% and close to 100%. WebWeidong Chen, Dean S. Venables, in Advances in Spectroscopic Monitoring of the Atmosphere, 2024. 3.2.1 Resonator theory. The optical resonator or optical cavity is the heart of the broadband spectroscopic methods discussed in this chapter. An optical cavity is an arrangement of two or more mirrors that creates a closed optical path around which …

WebOptical reference cavities are resonators for light and provide a way to precisely define an optical frequency. Optical reference cavities are used analogously to tuning forks for … WebOften there are optics in a system that define an optical axis, for example the center of curvature of two mirrors defines the optical axis of a Fabry-Perot cavity. The beam from the laser can be made to propagate along this axis by using a minimum of 2 mirrors. ... This can be achieved by placing a lens one focal length away from the beam ...
