Available Transmission Spheres
Transmission Spheres are used for testing spherical surfaces. These generate a reference wave against which spherical samples can be tested interferometrically. The Transmission Spheres are available with different radii (R(Transmission Sphere)) and usable diameters (D(Transmission Sphere)). In order to measure the entire spherical surface to be tested, the following condition must be met:
R/D(Transmission Sphere) ≤ R/D(test area).
The following graphs and tables can be used to select the objective for the respective inspection task.
*Note: Additionally, an optical connector is needed.
