Product Details
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.
Using the optional reticle eyepiece on Model 966A, width
measurements up to 0.040" can be made. 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.
Description
The Optical Micrometer is designed with a rugged housing and
easy-to-read vernier scale. Model 966 provides 100x power
permitting depth measurement up to 0.665". Model 966A provides
200x power, which allows depth measurement up to 0.260". Both
models are supplied with a standard tripod base that can be used
on flat or simple curved surfaces.
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.

Accessories
Six interchangeable mounting bases are available to accommodate
convex, concave, or compound surfaces. A micrometer light
adapter can also be used to illuminate the sample, making
measurement easier to read.
-
Tripod Base - Provides the greatest overall utility for flat,
simple and compound curved surfaces
-
Quadpod Base - Used for concave/convex curved
surfaces
-
Offset Tripod Base - Permits measurement of flat or curved
surfaces adjacent to protruding obstructions prohibiting use
of tripod base
-
Wedge Bipod Base - Used when intersection of planed surfaces
form angles of at least 80°
-
Translucent V-Block Base - Used for round surfaces, such as
tubing, and external angles; provides flat support for areas
with recesses on sides
-
Large Tripod Base - Used for applications requiring a larger
support area than provided by tripod base; primarily used for
small parts inspection
