Widely used for checking the flatness and parallelism of micrometer anvils, our optical parallels are specially designed to observe light wave interference fringes. These parallels use monochromatic light sources for observing fringes/light bands.
These parallels hold the following features and specifications:
Thickness of the four Optical Parallel appropriate for every quarter turn of the micrometer screw
One of the parallel is used for inspection of parallelism
Parallelism between the Anvil and the Micrometer screw measured by the number of light bands at each of the four positions of the micrometer screw.
Material:BK7
Diameter :25mm
Thickness:15~25mm
Flatness:λ/10
Surface quality:60—40scratch and dig
