  • UV Warning Signal

    511 - Solar Light Company Inc.

    The UV Warning Signal model 511 is designed to provide a real-time indication of the sun's UV intensity in an easy to read packaging. Great for outdoor areas; golf courses, country clubs, school yards, outdoor sporting events, amusement parks, ski slopes, beaches, and swimming pools.The concept behind the UV Warning Signal is that it take's the sun's radiation, changes the UV photons of light in the "skin sensitive range" into an electrical signal which activates one of the indicator lights corresponding to the World Health Organization and US EPA UV Index exposure categories. These exposure categories are represented on the UV Warning Signal by five high intensity colored LED indicator lights, and are visible, even in direct sunlight, from up to 50 meters. When in operation the UV Warning Signal illuminates the indicator light that corresponds to the level of UV radiation being received by the sensor.

  • Fiber Optic Multiplexer

    Ingellen Technology Co.,Ltd

    Fiber optic multiplexer is a device that processes two or more light signals through a single optical fiber, in order to increase the amount of information that can be carried through a network. Light wavelengths are narrow beams that ricochet through reflective optical tubing, sometimes over long distances, to provide instantaneous electronic signal processing at the speed of light. The optical fiber multiplexer serves incumbent and alternative carriers, cellular operators, ISPs, utilities, transportation networks, large enterprises, and small and medium-sized businesses. It is possible to split signals by varying the schedule or period of each transmission.

  • Particle Sensor

    HPM Series - Honeywell Sensing & Control

    The Honeywell HPM Series Particle Sensor is a laser-basedsensor which uses the light scattering method to detectand count particles in the concentration range of 0 g/m3to 1,000 g/m3 in a given environment. A laser light sourceilluminates a particle as it is pulled through the detectionchamber. As particles pass through the laser beam, the lightsource becomes obscured and is recorded on the photo orlight detector. The light is then analyzed and converted toan electrical signal providing particulate size and quantity tocalculate concentrations in real time. The Honeywell particlesensor provides information on the particle concentration forgiven particle concentration range.

  • Optical Isolators

    SYOPTEK INTERNATIONAL LIMITED

    Optical Isolator is a passive optical component that allows light to transmit in a certain direction while block light in the opposite direction. The working principle is based on the non-reciprocity of Faraday rotation. The light sources from back reflections and signals, which can cause instabilities and damage, can be well isolated by optical isolator through utilizing the Faraday effect of magneto-optical crystal. The Polarization Insensitive Isolator features low insertion loss, high isolation and excellent environmental stability and reliability. It is ideal for suppressing back reflection in fiber lasers and other high performance laser based fiber optics systems.

  • Erbium Doped Fiber Amplifier

    EDFA - Fibotec Fiberoptics GmbH

    EDFAs are based on the light amplification in erbium-doped fiber, which are optically pumped by means of 980 nm or 1480 nm light sources. In this way, the light of a larger wavelength within the C or L band applied to the input of the amplifier is amplified, thus widening the range of optical communication links. EDFAs typically operate in saturation and the average signal power determines the average gain. The dynamics of EDFA are unaffected by the sequence and dynamics of a digital signal or channel interaction in DWDM systems. As a result, multiple channels can be bundled within the total erbium spectral amplification bandwidth. However, the total average output power in both cases is determined by the saturation power of the specific EDFA.

  • Integrating Spheres

    Ophir Photonics

    Integrating spheres are used especially for measuring divergent light sources such as LEDs. The light is introduced through the input port, then reflected many times by the highly reflective interior of the sphere until it illuminates the inner surface uniformly. A detector samples a small fraction of this light to measure the total power input. Ophir integrating spheres have a highly reflective diffuse white coating for measurements independent of beam size, position and divergence. There are several sphere sizes, apertures and wavelength regions available. The large IS6 series has 2 configurations for measuring divergent or parallel beams (see diagram).
