Projection lamps use a built-in reflector to concentrate light in a particular direction. They are used in applications such as slide projection, microfilm, overhead projection, movies, medical / scientific instruments, airport runways, and others

Projection screens are used to display images from overhead and video projectors

Specialty Optical Polarizers use the optical properties of a medium to alter the polarization of light. This category includes radial polarizers, azimuthal polarizers, elliptical polarizers, etc

Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available

Audio visual service providers design, integrate, and install multimedia equipment for corporate, production, and broadcasting applications.

Welding and fabrication services weld and fabricate a variety of materials. They may also perform services such as machining, CAD support, and field welding.

Welding machines and joining machines include all manner of devices used for welding, brazing and soldering.

Parabolic reflectors and ellipsoidal reflectors are used to maximize illumination or projection system output by increasing light source efficiency

Flat panel displays (FPDs) are thin, flat, electronic devices used to display data. They are commonly used in notebook computers. Most styles include the housing and ports necessary to connect them to a computer.

Multi-screen display controllers are used to control and project multiple images on the same screen.

Projectors receive data from a computer or video source and project this data onto a screen via internal light sources, power sources and converters.

Shaft-hub locking devices frictionally clamp gears, pulleys, flywheels, and other components to a shaft without the need for threads or keys.

Fresnel lenses resemble a planoconvex or planoconcave lens that is cut into narrow rings and flattened. If the steps are narrow, the surface of each step is generally made conical and not spherical.

Laser welding services use high-powered laser welding equipment to fuse materials together.

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.
