Beam Expander

Purpose of Use

• The Beam Expander is used when a test piece is bigger than the aperture of the interferometer.
• When measuring a large aperture test piece, the Beam Expander expands the laser beam aperture.

Specifications, Features, and Benefits

• It is possible to measure entire surface by one sheet of interferogram when the flatness measurement with a large aperture occurs.
• There are three types of Beam Expanders, and each of them are possible to expand measurement beam aperture of Ø100 to 8 inches (approx.200mm), 10 inches (approx.250mm), and 12 inches (approx.300mm).
• When the condition becomes a large aperture, measurement will become very difficult on attachment of a phase shift mechanism, the turbulence of air, and the problem of vibration, but by using our product of an instantaneous phase shift, Fizeau interferometer Intellium™H2000, more stabilized measurement is possible and expands applied ranges.
• A compact design. Possible to install in conserved spaces.
• Vertical or Horizontal Installation
• Outstanding cost performance
• We also prepare references.
• We consult larger aperture at customers' requests.
