Micrometers are instruments for precision dimensional gaging consisting of a ground spindle and anvil mounted in a C-shaped steel frame.  Noncontact laser micrometers are also available

Laser micrometers measure extremely small distances using laser technology

Dimensional gages and instruments provide quantitative measurements of product or component dimensional and form attributes such as wall thickness, depth, height, length, inner diameter (ID), outer diameter (OD), taper or bore.

Calipers typically use a precise slide movement for inside, outside, depth or step measurements. Some caliper types are used for comparing or transferring dimensions.

Depth gages are used to measure of the depth of holes, cavities, or other component features.

Rotary positioning stages are devices with tables or shafts that may be rotated to any angular position. They may be driven or simple slides.

Height gages are used for measuring the height of components or product features.

Thread gages are dimensional instruments for measuring and/or verifying thread size, pitch or other parameters.

Bore and ID gages are designed for internal diameter dimensional measurement or assessment.

Dovetail slides are linear motion devices that allow motion and positioning along a linear axis.

Thickness gages are used to make precise dimensional measurements on a wide variety of coatings and materials including steel, plastic, glass, rubber, ceramics, paint, electroplated layers, enamels, etc

Linear slides are simple linear motion devices composed of a stationary base and a moving carriage. Linear stages are slides with a drive mechanism that provide controlled, precise positioning along a linear axis.

Microscope stages are platforms where specimens are placed for observation with a microscope. They are often equipped with a mechanical device which holds the specimen slide in place, but allows the back-and-forth and side-to-side movement of the slide.

Masters and setting gages provide dimensional standards for calibrating other gages.

Piezoelectric actuators are devices that produce a small displacement with a high force capability when voltage is applied.
