Custom Transmission Spheres
Computer-generated Holograms can be designed to create every spherical wavefront needed for a specific measurement task. These CGHs are particularly well-suited for testing cylinders and spheres with large radii of curvature. Testing of concave and convex surfaces is equally possible and meets the highest quality standards.
Features and Benefits
CGHs with Freely Selectable Focal Length
Our diffractive interferometer lenses are suitable for convex and concave surfaces. We are able to offer focal lengths or F-numbers between f/0.7 and infinity. Our diffractive interferometer lenses are compatible with all standard bayonet connections for interferometers.
Compact Measurement Setup with Maximum Test Diameter
Our compact measurement setup offers a maximum test diameter. For convex surfaces, we create the specifically adapted object wave directly behind the diffractive optics to achieve a larger measurement diameter. When testing concave surfaces, there is less interference due to the shorter measuring distances achieved using the diverging diffraction order.
Easy Handling and Optimum Adjustment
Our optical components and systems are designed for easy handling and optimal adjustment. Our goal is to help you achieve the best results as simply, quickly, and cost-effectively as possible. This also applies in particular to the system integration and handling of our test lenses. All diffractive inspection lenses can be equipped with additional auxiliary holograms as an alignment aid and for radius measurement with relative precision of up to 50 ppm.
