Precision Lapping
Our lapping services not only include all optical materials and glasses, we also lap metal/alloy, alumina and ferrites. Using double-sided planetary machines, we focus on components when both sides need lapping to precision tolerances. The surfaces are lapped simultaneously held in carriers so no need for fixing or clamping, lapping the components in a stress free process without thermal distortion. Our lapping department handles 1 off to 1,000’s of components a day.

In many optical applications the surfaces need diffusing, we can lap one or both sides to a stated micron finish 5 microns to 100 microns. More information can be seen on our diffusers page.
