Diamond Machined or Polished?.

Even the latest diamond machining centres will produce optics with flycutting arcs, target patterns, and other artefacts in the optical surface. These cause laser light to diffract and scatter, and for visible light the losses can be so great that the beam is completely lost after several reflections.

Often diamond machined optics are “post polished” to remove the waviness and ripple in the machined surface. Even a casual observer can see these surface problems. Click here for a picture of a typical diamond machined surface. Sometime the cutting lines are seen as a “rainbow blaze” on a reflective surface.

Poor alignment of the cutting tool can leave a central spike in the mirror click here.

LBP have developed chemical polishing techniques used in the production of high quality UV optics, for producing infra red optics. Electroless nickel is an amorphous metal that can be polished to extreme smoothness, just a few angstroms of surface roughness.

The combination of chemical polishing and amorphous coatings mean LBP optics have the smoothest flaw free surfaces available.
