| Diamond Turning |
 |
| This department
contains the most advanced diamond turning machines available today.
These, together with the department's know-how enable Ophir to achieve
the highest levels of accuracy and surface quality on a wide range
of substrates including Ge, Si, ZnSe, ZnS, ZnS Multispectral ,
CaF2, AMTIR, PMMA, Al and Cu. |
|
 |
The department
is equipped with dual axis turning machines and also boasts
advanced testing equipment such as Zygo interferometers , a
Talysurf profiler and
Zygo NewView optical profiler to measure surface form and roughness,
and interferometers that use CGHs (computer generated holograms)
to test both aspheric and diffractive surfaces.
Ophir can machine reflective and refractive materials, as well
as acrylics and other plastic based materials, round and truncated
optical elements, perfect spherical or complex aspheric and
diffractive surfaces. Paraboloids, ellipsoids and hyperboloids,
with on and off axis symmetry, are all standard demands to the
Ophir diamond turning team. With its diamond turning experience
Ophir's team of engineers is responsible for the manufacture
of many highly specialized and customized elements. The unique
strength of the Ophir diamond turning department stems from
our exploration of new production methods. This exploration
enables us to produce one-off and high volume cost-effective
aspheric and diffractive elements to extremely high standards.

Years of diamond turning experience enable our engineers
not only to produce according to a given design, but also to work
together with customers optical design teams to provide alternative
solutions to improve the overall performance of their designs |
