Ronchi test

Ronchi-Test {m}optics

• Testing of the figure is usually done by a Foucault knife-edge test or Ronchi test in amateur telescope making and with very sophisticated null testers on research telescope optics.
• In 1922 Ronchi published work describing testing methods for optics using simple equipment. The Ronchi test is widely used in amateur telescope making. The Ronchi ruling also bears his name.
• Some amateur telescope makers use a similar test called a Ronchi test that replaces the knife edge with a "grating" comprising several fine parallel wires or an etching on a glass plate.
• Some telescope makers use a variant of the Foucault test called a Ronchi test that replaces the knife edge with a grating (similar to a very coarse diffraction grating) comprising fine parallel wires, an etching on a glass plate, a photograph negative or computer printed transparency.
