The addition of a software module-belonging to OptiAngle® (another subsystem of OptiTest®) and the use of specific mechanical fixtures converts the OptiSpheric® to a powerful tool for angle measurement of:
 

wedges and filters;

90°-prisms;

parallelism of plane plates;

deviation angle through wedges and prisms;

mirror tilt;

alignment of CD-optical heads;

wobble of rotating glass disks;
 
The angle measurements of plano optics are made directly with the autocollimator of the measuring head (without additional head lenses). The mechanical fixtures includes three-ball supports, prism fixtures, etc. to be mounted on the instrument tilt table.

The unique performance can be further increased by adding software modules and accessories from OptiCentric® (another subsystem of OptiTest®).
 
Applications include measurement of centering errors in transmission and reflection. Using appropriate accessories even the alignment or cementing of optics can be carried out. With this extension of the measuring capabilities the OptiSpheric® becomes a valuable and indispensable quality tool for any optical shop or laboratory. The largest range of accessories for accurate and efficient measurement of centering errors are available: precision rotary holders, lens rotation devices with vacuum, ultra precision air bearing tables, etc. Illumination devices have been specifically designed to provide reliable results even in difficult applications as surfaces with AR-coating. The software module provides fast and accurate results, shows the size and direction of the decentration and evaluates even extremely weak and blurred images.
