Dear students todays video is about flatness testing by optical flat in monochromatic light source. In this practical you rest a optical flat and due to light source fringe pattern appear. and from this fringe pattern you can interpret whether that surface flat or convex , concave.
When your surface is perfectly flat then straight fringe patter appear. convex surface then away from center. Krypton 86 is monochromatic light source.
