Light Interference Plates IP-5N


【Product Description】

Specially made optical flat glass plates for observation and counting out the interference fringes.

【Overall Advantages to Users】

These plates have a high optical flatness to create clear interference fringes using a monochromatic source like a Sodium lamp, and a good enough area (around 50 x 200 mm) for counting out the interference fringes or observing the fringe patterns.


  • Interference fringes
  • Interference of light
  • Reflection and Refraction
  • Light wavelength
  • Monochromatic light source




【To all users】

  • The high optical flatness on the plates can provide a higher contrast of shades between dark and bright bands so that you observe the clear interference fringes with a pattern of evenly spaced alternating bright and dark bands.
  • The high contrast interference fringes on enough length of the plates enable you to calculate the thickness of a thin material such as a cellophane film or a hair based on the number of lines counted and frequency of a monochromatic source (like a Sodium lamp).
  • Optical flatness glass plate: 2 pcs, 50 x 200 x 6 mm
