WebWe have constructed and tested a vacuum-spaced Fizeau wedge wavemeter that is suitable for measuring the wavelength of pulsed or continuous-wave lasers over the range of 630 nm to 200 nm. A Lasertechnics Model 100 Fizeau wavemeter was modified for ultraviolet operation and demonstrated an accuracy of 1.6 parts in 10/sup 5/ at 248 nm. … WebAug 1, 1984 · The wedge spacing of a Fizeau wavelength meter is an important parameter in the conversion of fringe patterns into wavelengths of interfering light. In this paper, …

WebHere we derive, from first principles, the equal fringe spacing for a Fizeau Wedge between glass slides as pictured below. Consider vertical illumination and only two reflections … WebA white-light Fizeau interferometer is described. Commonly, white-light fringes can be produced only by using a virtual wedge instrument such as a Michelson interferometer. By use of a series arrangement of a Fabry–Perot interferometer in front of a two-beam Fizeau interferometer, white-light fringes can be produced. For white-light fringes to be obtained, … smart guy anime

WebThe paper presents analysis of the response in transmission for Fizeau interferential wedge in order to use this optical element as a beam splitter with a controllable ratio between the transmitted and the incident power. The wedge is formed by two highly reflecting flat surfaces inclined at a small angle. hillsboro landfill hillsboro oregon
