The “plate” required for glass lens processing must have the correct shape, be finished to the correct radius, and be accurate enough to allow easy optical polishing.
By using the correct plate according to the accuracy of the test plate, lenses with the correct accuracy can be made.

The radius (spherical surface accuracy) of the plates manufactured by us is extremely high precision.
The appropriate R is shifted according to the number of sand, and R can be managed by the number of Newton rings, making the plate matching work at the user’s site nearly unnecessary.

R production is performed to match the test plate in various materials. We can support from very small R to large apertures.
