This machine is designed primarily for the production of high quality plano-optics, such as proof flats, etalons, prisms, filters, windows and ring laser gyroscope blanks.
It has a unique feature in its use of a dynamic air bearing which supports the rotating mass of the pitch lap and its backing plate, drive being through a circumferential belt.
The virtual elimination of vibration, together with a recirculation water system to control pitch temperature, lead to dramatically improved performance.
It can typically produce flatness within λ/20 (He) over surfaces up to 300mm diameter, and surface texture well below10ÅRMS.
