| CNC Polishing |
 |
| The conventional
polishing department at Ophir produces spherical elements, windows,
domes, prisms and mirrors from all known materials for the IR spectrum
and has additional capabilities in the visible range and uv spectrum.
This department is unique in its abilities to produce a wide range
of high precision elements in prototype and one-off production, as
well as high precision elements in mass production. |
|
|
During its years of operational experience, unique techniques of micro-polishing
have been developed which enable Ophir to easily produce elements
needed for high transmission and low scattering and absorption applications.
Manufacturing capabilities include the most advanced machines existing
on the market for grinding, polishing, centering and shaping of optical
components. This technically advanced machinery is perfectly complemented
by conventional optical manufacturing equipment, proven over many
years to produce state-of-the-art precision elements. |
| Ophir is capable
of producing elements from a minimum diameter of 3mm to a maximum
diameter of 350mm with dimensional tolerances of 0.01mm. Quality achievements
include surface finish of 10-5 scratch and dig, parrallelism of 1"
and irregularity of λ/10 P-V at 0.633µ on Germanium (Ge),
Silicon (Si), Zinc Sulfide (ZnS), Zinc Selenide (ZnSe), Calcium Fluoride
(CaF2), Galium Arsenide (GaAs), PMMA, Quartz, Fused Silica, and
other exotic materials, as well as most types of glass. |
