Optical micrometer
Taber Industries

The Optical Micrometer is capable of making non-contact measurements on any surface, curved or flat. This instrument is useful for measuring depth of scratches, fractures, crazing, embedded voids and thickness of transparent materials (i.e. glass, acrylic). It can also measure scratches, cracks, corrosion, pits, blemishes, small dents and other imperfections. This portable instrument is ideal for field applications such as windshields, leading edges, airframes, fuselage skin, propeller blades, rotor blades, turbine blades, coated surfaces, plus many more.

To take a surface measurement, the operator positions the Optical Micrometer over the area to be examined. After proper focusing, the operator takes a reading at the highest surface in the specific area. A second reading is taken at the lowest surface, and measurement is calculated by computing the difference between the two readings.
