Infrared Caps, Lenses, Color Filters and Windows are all used to block or view particular types of infrared light. Color Filters filter out unwanted light or color; caps block light, while lenses change the filtering, color and form of the light.
Generates voltage changes due to variations in detector temperature resulting from the power focused on it, or generates changes in voltage due to photo-electron interactions in the detector material.
Infrared Emitters are designed for infrared distribution systems. They allow users to send signals from remote controls or other controllers directly to specified equipment.
Infrared Receivers are electronic devices that are specifically designed to receive and process infrared electric signals.
Laser Components and Accessories help to change the direction of the laser, control its movement or make the operation easier and safer. Some examples would include laser detectors, protective eyewear, actuators and controllers
Laser Diodes
(58 Companies)
Uses light-emitting diodes to produce stimulated emissions in the form of coherent light output.
Laser Receivers
(12 Companies)
Laser Receivers are electronic devices that are specifically designed to receive and process light pulses.
Light-Emitting Diodes (LEDs) are semiconductor diodes that emit light when electrical currents are applied in their forward directions. LEDs can be infrared, visible or ultraviolet and used as indicator lights, flashlights and area lighting.
Optical Switches enable signals in optical fibers or integrated optical circuits (IOCs) to be selectively switched from one circuit to another.
Consist of a light source (generally an infrared LED emitter) and a light detector (generally a photocell, photodiode, or other type of photodetector), all housed in a single package.
Optoelectronic Interrupters automatically suspend and resume an optical electric current by opening or closing a circuit.
Optoisolators
(45 Companies)
Optical devices that allow light to be transmitted in only one direction. Used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems.
Optosensors
(19 Companies)
Optosensors use visuals and optics that collect and analyze information. Often used as warning systems alerting users of dangers or hazards, such as when a forklift is backing up.
Photo Cells
(27 Companies)
Photo Cells are light-sensing cells. They are most often used to activate controllers, especially at dawn or dusk. They can also detect product location in machine operation.
A Phototransistor is a semiconductor device that has light-sensitive electrical characteristics. They often have windows to allow light to fall on their active surface.
Photodetectors
(54 Companies)
Photodetectors are sensors of light or other electromagnetic energy.
Photodiodes
(53 Companies)
Two-electrode, radiation-sensitive junction formed in a semiconductor material in which the reverse current varies with illumination.
Photoelectric Alarms and Controls analyze and determine if systems are safe and in proper working order. Photoelectric Controls are used to control a circuit or piece of equipment in response to a change in incident light ( photoelectric fire alarms).
Photoelectric Diodes are electrical devices that allow electrical currents of light to pass through it in only one direction. It is like a light valve.
Photointerrupters are devices that are designed to stop the flow of a beam of light, either momentarily or for an extended period of time.

15-Minute on-demand multimedia web casts covering the latest product developments.
Currently, optical sensors are not the mainstream use in mice and trackballs. With consumers demanding enhanced capabilities as well as smaller technology for their computer peripherals, using lasers or LEDs in smaller mice and trackballs is one of the most effective ways of achieving that result. Laser technology makes it possible to track on various surfaces, so you’re not limited to your desktop, as well as providing a higher degree of precision in tracking.
This presentation provides information on challenges and resolutions with mouse/trackball design, from concept to creation. Avago will review the different optical navigation techniques, how the tracking actually works and what can be done to improve upon it. Answers to key challenges in designing very thin mice (less than 5mm) as well as optical sensor capabilities in trackball technology and design will be provided as well as recommendations.
At the end of this presentation, you will know how the laser technology works in tracking, how it can work in a small mouse and other design considerations, and future trackball technology.
