Our
extensive Quality Assurance controlled processes are ISO 9001:2000
certified. Ophir has years of experience working according to
military standards for all levels of performance specifications.
Our QA 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 recently, the only methods of measuring 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.
Previously, in spite of the 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. This was 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 that eliminates the disturbance, thus enabling interferometric
testing of diffractive surfaces for the first time. |
