What types of measurements can be taken with a laser scan micrometer? A major benefit of laser scan micrometers is how versatile they are in terms of types of measurements they are able to complete. Due to this versatility, there are a range of measurements that fall under the domain of laser scan micrometers. These include, but are not limited to, in-line glass fiber or fine wire diameter, outer diameter and roundness of cylinders, thickness of film and sheet, gaps between rollers, film sheet thickness, taper and form, outer diameter of optical connector and ferrule, outer diameter of opaque or transparent cylinders, X- and Y-axis electric cables and fibers, spacing of IC chip leads, disk head movement, and tape width. Additionally, laser scan micrometers can be used in pairs, thus serving as a dual system for measuring a larger outside diameter of a part or object.
