  • klaasist plaat mõõtevahendite tööpindade tasapinnalisuse mõõtmiseks
  • optical-grade piece of glass lapped and polished to be extremely flat on one or both sides, usually within a few millionths of an inch (about 25 nanometres)
tasaparalleelklaasplaat preferred
Usage examples
  • Tasaparalleelklaasplaate kasutatakse koos monokromaatilise valgusega, et mõõta interferentsi abil teiste pindade tasasust, olgu need siis optilised, metallilised, keraamilised või muud.
Good to know
  • Kui tasaparalleelklaasplaat asetatakse teisele pinnale ja valgustatakse, peegelduvad valguslained nii plaadi alumiselt pinnalt kui ka pinnalt, millele see toetub ning see põhjustab nähtust, mis sarnaneb õhukese kile interferentsiga.

optiline plaat variant
optical flat preferred
Usage examples
  • Optical flats are used with a monochromatic light to determine the flatness (surface accuracy) of other surfaces, whether optical, metallic, ceramic, or otherwise, by interference.
Good to know
  • When an optical flat is placed on another surface and illuminated, the light waves reflect off both the bottom surface of the flat and the surface it is resting on, and this causes a phenomenon similar to thin-film interference.
