Abstract: An optional method of demonstrating thin film interference fringes with a laser uses a microscope slide glass cover in place of the normal mica sheet. An 18-by-18-mm. square glass cover with a nominal thickness of 0.15 mm. is used. The technique provides unique reflection fringes while allowing demonstrators to project the transmission fringes on a secondary viewing screen angled to the primary screen.
