This product (Light Interference Plates IP-5N) includes optical flat glass plates specially designed for observing and counting a pattern of interference fringes visible as light and dark bands.
【Overall Advantages to Users】
Each of the glass plates has the flatness high enough to form a series of alternating/contrasting interference fringes visible as dark and light bands with equal spacing.
Another advantage of the glass plate is its sufficient size (50 x 200 mm) that helps a user easily calculate the thickness of a thin material such as a cellophane film or a human hair based on the number of fringes counted and a known frequency of a monochromatic light source (like a sodium lamp).
