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.

Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources.

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

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

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.

Plug and pin gauges are used to compare hole and slot dimensions or locations to specific tolerances. This product area includes go gauges and no-go gauges. 

Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors.

Snap gages are used in production settings where specific diametrical or thickness measurements must be repeated frequently with precision and accuracy.

Ring gages are used for go / no-go assessment compared to the specified dimensional tolerances or attributes of pins, shafts, or threaded studs.

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance.

Laser cutting machines, laser welding machines and laser marking systems use high-powered lasers to cut, trim, perforate, weld, or join a variety of materials in plate or sheet form
