12% of Ophir's workforce is involved in our extensive Quality Assurance
process. ISO 9001:2000 certified, Ophir has over 20 years of experience
working according to military standards across all levels of performance
specification. Our QC department uses an effective combination of
the world's most advanced testing and measurement equipment as well
as unique techniques developed at Ophir.
Ophir has developed and assembled a new holographic measurement setup
for interferometric testing of aspheric and diffractive surfaces.
Until now, the only ways to measure the power and irregularity of
diffractive surfaces were based on scanning the surface (with or without
mechanical contact) to obtain the cross-section profile of the surface.
In spite of the many advantages of interferometric testing over cross-section
profile measurements, such as short measurement time and full aperture
testing, interferometric testing was impossible for diffractive surfaces
due to interference effects of the test wavelength with the diffractive
steps present in the surface under test. Ophir's setup makes use of
a unique technology which eliminates the disturbances caused by interference
enabling for the first time, interferometric testing of diffractive
surfaces. |
