Standard of flatness: its application to Fabry-Perot interferometers

This article briefly describes the first attempts to make liquid and solid standard flats. The plane surface of 100-mm diameter polished on a cylindrical block of CER-VIT does not show any difference greater than lambda/270 with respect to a perfect plane over a circle of 70-mm diameter. After one y...

Description
Summary:This article briefly describes the first attempts to make liquid and solid standard flats. The plane surface of 100-mm diameter polished on a cylindrical block of CER-VIT does not show any difference greater than lambda/270 with respect to a perfect plane over a circle of 70-mm diameter. After one year of use no deformation has been observed.
