INTERFEROMETER VI-direct Typical Applications Flatness Measurements of Surfaces This setup is used for the measurement of surface flatness of plane elements such as mirrors, prisms and windows. For this set-up a transmission flat, a mount for the specimen (e.g. a self-centering holder) and a 2-axes adjustable mount are required. Wave-front and Wedge Angle Measurements of Plane Elements This setup is used for the measurement of the wave-front deviation of plane elements and for wedge angle measurements. For this set-up two transmission flats, possibly a mount for the specimen (e.g. a...

Info: By the combination of an optical connector with a transmission sphere, the innovative transmission sphere system allows a considerably increased measurement range and a 60% superior illumination compared to classical transmission spheres. One optical connector is needed. It can be combined with all transmission spheres. The principle and a selection guide are shown on page 13. The use of transmission spheres of other manufacturers is possible, too. DescriptionArt.

INTERFEROMETER VI-direct Choice of Transmission Sphere For testing of spherical surfaces so called transmissions 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: /D (Fizeau) ≤ R/D (surface under test) For the best choice of transmission spheres for respective measuring tasks the following graphics and tables can be used....
