Equipment & Capability
We employ the latest slow-tool servo technology on our 3-axis machines enabling us to produce non-rotationally symmetric surfaces including toroids, cylinders and free-forms. We can produce bi-aspheric lenses 4mm in size to hemispherical domes up to 350mm in diameter. All our machines incorporate the latest hydrostatic slide-ways and linear motor technology. They are also fitted with heavy-duty spindles.

We have extensive metrology to ensure the demanding characterization of aspheric and hybrid surfaces. Surface profilometry is performed with our Talysurf PGI Series 2 and PGI 1240 instruments. Mild-departure aspheric surfaces can also be directly characterized using our Fisba phase-shifting interferometer. Our Talysurf CCI 3000A white light interferometer provides non-contact measurement of surface quality and diffractive features. The diamond-turning facility is supported by the in-house capabilities of Phoenix Optical Technologies to generate blanks, produce custom tooling and polish non-diamond-turned surfaces. The combination of equipment stability and skilled machinists lead to vastly improved form control and surface finishes on all materials. Phoenix is ISO 9001:2000 certified since 1997. We hold the following typical form and roughness tolerances. This table is meant only as a rough guide as actual specifications are strongly dependent upon component geometry:
