Lapmaster Polishing Department

Specialist Polishing Area

This is where very flat optics are produced on our three 48" lapmasters. Depending on the material and the dimensions, flatness specifications of lambda/20 at 633nm can be achieved. It is usually the harder crystalline materials that are polished by this method and recent development work has meant that we can now produce higher flatness specifications on even thinner optics.

In addition to working with the IR and UV crystalline materials Crystran has specialised in over the last 25 years, we are now producing large, very flat optics in Fused Silica and Glass for use in a range of laser applications.
