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

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

Spherical lenses, also known as singlets, are transparent optical components consisting of one or more pieces of optical glass with surfaces so curved that they serve to converge or diverge the transmitted rays from an object, thus forming a real or virtual image of that object.  This area includes micro spherical lenses as well.

Video camera lenses attach to video cameras for use in machine vision, quality monitoring, security, and remote monitoring for industrial and commercial operations. This search form does not cover consumer video camera lenses. 

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.

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.

Antennas are structures or devices used to collect or radiate electromagnetic waves.

Light-emitting diodes (LED) are PN junction devices that give off light radiation when biased in the forward direction. LEDs are used in a wide variety of indication applications.

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. 

Plastics and plastic materials are organic, synthetic or processed polymers that are supplied as raw materials or stock shapes. They typically consist of thermoplastic or thermosetting resins and can be made into many forms.

Lighting fixtures and lamp sockets produce artificial light in industrial areas or workspaces, and mechanically hold and electrically connect lamp bulbs to wiring.

Iris apertures are used to manually vary the intensity of light, and the angle of incidence, of a cone of light.

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).

Optical lens assemblies are composed of a number of lenses mounted for a particular imaging function. These can include objectives, collimators, gauging lenses, etc
