About This Product
These precision Ronchi slides contain a 1/2” x 1” ruling pattern on a standard 1” x 3” microscope slide. The Ronchi Ruling pattern
consists of evenly spaced opaque and clear lines. The pattern frequency is listed in terms of Line Pairs Per Millimeter (LP/MM).
The pattern is formed
in durable double layer evaporative Chromium (Optical Density >3.0) on a stable 1mm Soda Lime Glass substrate.
Ronchi Slides can be used in the
determination of optical resolution, MTF, field distortion, and parfocal stability. Several frequency variations are available from 5LPMM to 600LPMM. For UV
applications, all slides are available on Fused Silica substrates. For biological applications using UV light, a phosphorescent backed version is also available.
