Non spherical lenses machined with diamond

Non spherical lenses are now widely used in industrial, defense, and consumer applications. Taylor Hobson is the top metrology supplier for non spherical optical manufacturers.

Single point diamond cutting (SPDT) can quickly and effectively manufacture high-precision non spherical lenses. The sub wavelength shape accuracy specification means that metrology is crucial to the manufacturing process. TAYLOR HOBSON's Form Talysurf PGI non spherical measurement system sets a global standard for lens users, providing shape accuracy as low as 1/10 λ. Please refer to the detailed description in the Talysurf link below.

The use of non spherical analysis software

By using TAYLOR HOBSON's outstanding algorithm, in-depth analysis of non spherical optics can be conducted. PGI comes standard with shape error and surface roughness parameters, radius * optimization, SAG table, and astigmatism analysis functions. If necessary, a unique derivative coefficient module can also be provided to directly calculate the non spherical data of the part.
