The LI10 Fizeau Interferometer is ideally suited to a wide range of flatness measurement operations on polished specimens up to 102mm (4”)Ø.This unit is appropriate for use in both optical component production and research and development laboratories.

This interferometer, offers a rapid and accurate method for the optical measurement of polished surface flatness. Its reference flat, has a flatness of lambda/10 and does not come into contact with the surface under test. This allows a contour map, or interferogram, to be produced by the display of reflections between these two surfaces.

• High precision flatness measurement of polished samples to lamda/10

• 3D imaging & analysis capacity

• Measure 0.335µm per fringe with high clarity

• Image & analyse fringe patterns on materials from 1” to 6” Ø
