Since 1972 Lap Tech has produced custom quartz resonators. The experience gained in the lapping and polishing of quartz is now being made available to industry in general.
From the smallest crystalline substrates to various metal items and correcting of allumina plates, Lap Tech can provide a very wide range of lapping and polishing services.
Unlike most optical fabricators that rely solely on single side processing, our facility can process very small thin sections to large items using single or double side processing.
Our experience is primarily very flat and parallel quartz substrates for frequency control but also encompasses metal and ceramic processing to the same exacting tolerances.
Chucks designed to support silicon wafers during the polishing process, eventually wear reducing the overall quality of the Silicon wafers. Laptech can recondition plates of Aluminum Oxide or Silicon carbide using a propriety lapping technique, returning the plates clean and ready for use.
