Choice of Transmission Spheres

For testing of spherical surfaces so called transmission spheres are used. These generate a reference wave which can be tested against a spherical sample interferometrically. Transmission spheres are available with different radii (R(Fizeau)) and usable diameters (D(Fizeau)). To measure the whole spherical surface under test the following condition must be fulfilled:

R/D(Fizeau) ≤ R/D(surface under test)
 

The technical data and the corresponding graphic will help you to select the optimum transmission sphere for your measuring task.

Transmission Sphere System

 

The transmission sphere system for the Interferometer VI-direct 100 consists of an optical connector, which includes parts of the lens system and a transmission sphere. Therefore the transmission sphere can be reduced to a minimal number of optical components. The arrangement of connector and transmission sphere results in a larger aperture diameter and in a larger measurement range in comparison to standard 4'' transmission spheres. Also is a transmission flat is available which generates in combination with the optical connector a plane reference wave with diameter 130 mm. This increases the measurement diameter of an Interferometer VI-direct 100 by 30%.
