Interferometer Flatness Measuring
The Lapmaster/LAMTech TOPOS and SPI series of Interferometers both feature Grazing Incidence flatness inspection and the measurement capability for grinding, lapping and polishing applications. Reflective surfaces, matte surfaces and ground surfaces can all be optically measured. The compact and cost-effective SPI series (Models #75 & #130) are contact flatness measuring gauging systems and utilize grazing incidence interferometry, providing the capability to measure surface flatness...

Single and Double-sided Optical Flats
Advanced Optics manufactures both single-sided and double-sided optical flats which may be used as a reference (test plate) against which the flatness of an unknown surface may be compared or as optical windows. Single-sided flats are typically used as a reference (test plate) and may be made of either low expansion borosilicate glass, fused silica or Zerodur. Surface flatness of 1/4 , 1/10 or 1/20 wave are available in either fused silica or Zerodur and 1/4 and 1/10 wave in low... (read more)
