Optical Communication
Ultra-precision tooling for optical components requiring stable geometry, fine surface quality, and repeatable transmission performance
Optical Lens
Diamond tooling for aspheric, freeform, and Fresnel optics where form accuracy and surface finish define optical performance
Four optical application areas where geometry, surface quality, and repeatability directly define performance
Nanometer-edge MCD tools for diamond turning of optical lenses and mold inserts — mirror surfaces straight off the machine.
Sharp-edged single-crystal diamond tools that cut Fresnel grooves, aspheres, and freeform surfaces in one continuous turning operation.
Precision V-groove MCD tools for fiber array substrates and NIL mold masters, holding groove angle and pitch consistent across hundreds of channels.
Single-crystal diamond tools for micro-lens array molds — the lenslet form accuracy that sets coupling efficiency in optical engine assemblies.
Precision diamond tools designed for optical performance
Standard ISO-geometry diamond inserts for mirror turning of non-ferrous and plastic optics on conventional and ultra-precision lathes.
Sharp-nose single-crystal tools with defined arc radius, cutting aspheres, freeform surfaces, and Fresnel grooves at nanometer-level edge quality.
Single-point bits for fly-cutting and planing — light-guide dots, V-grooves, and micro-structures cut straight into mold surfaces.
Controlled-radius ball tools for milling MLA cavities, freeform pockets, and 3D micro-structures unreachable by turning.
From application requirement to a proven tool solution
Evaluate workpiece material, properties, and machining behavior.
Analyze optical geometry, profile requirements, and critical features.
Define form accuracy, surface finish, and optical surface requirements.
Optimize tool geometry, cutting edge profile, and edge condition.
Verify tool geometry, surface quality, and repeatability against specification.
