Motor and generator winding services suppliers specialize in producing custom motors, generators and custom windings per customer specifications, as well as companies that specialize in motor repair and refurbishing.
Venturi vacuum generators use the flow of motive fluid such as air, steam, or liquid to evacuate air.

Optical Comparators

(115 companies)
Optical comparators are instruments that project a magnified image or profile of a part onto a screen for comparison to a standard overlay profile or scale.

Optical Crystals

(177 companies)
Optical crystals are transparent in different spectral regions, depending upon the crystal material.

IC Signal Generators

(42 companies)
IC waveform generators provide several different waveforms or functions at the desired frequency.
Digital delay generators produce pulses at precise, programmed intervals to trigger devices under test. They are also used for gating, timing, triggering, and syncing.
Optical choppers are mechanical or electronic devices that pass and then interrupt a beam of light for a known brief interval. Optical shutters are used to control the amount of time that a light sensitive material is exposed to radiation.
Generator heads and alternators convert mechanical energy into electrical power through electromagnetic induction.
Tachometer generators and tachogenerators are small AC or DC generators that output a voltage in proportion to the rotational speed of a shaft. They are capable of measuring speed and direction of rotation, but not position.

Optical Sights

(15 companies)
Optical sights are optical lens assemblies used for aiming a gun. Categories include telescopic sights, visible sights, and infrared sights.

Optical Tables

(23 companies)
Optical tables dampen working surfaces with superior flatness. They are used in the precision mounting of optical components.

Optical Breadboards

(10 companies)
Optical breadboards are flat surfaces with regularly spaced threaded holes that can be placed on a table or workbench and used for precision mounting of optical components.

Optical Mounts

(95 companies)
Optical mounts are specialized holders designed for use with a variety of optical assemblies.

Optical Rails

(12 companies)
Optical rails mount to optical tables to support components and instruments in a straight line, while retaining the freedom to quickly change their relative spacing.

Optical Apertures

(24 companies)
Optical apertures and optical slits control the diameter of beams from light sources.
