| Quality test lenses for workshop and laboratories |
| |
 |
Test lenses and software for interferometry are mainly used to check the form of plane, spherical and aspheric surfaces in optics workshops and laboratories. Special applications of test lenses and software include wavefront analyses, homogeneity checks, image quality checks, tolerance threshold analyses and the simulation of optical systems.
