  • Reflectance/Transmittance Test Set

    RT-500 - Lumetronics

    An Integrating Sphere is a hollow sphere which has its interior coated with a paint that is nearly perfectly diffuse or Lambertian and which has extremely high reflectance. Light energy introduced in an integrating sphere is reflected from the wall and distributed uniformly around the interior. A detector which is placed at a hole or 'Port' in the sphere wall sees an output which is completely independent of the angularproperties of the input light. The independence of the output of a sphere from the angular properties of the input and the uniform internal distribution of light make integrating spheres ideal for many uses.

  • Automobile Laser Night-Vision

    ALV - China Sheenrun Electronics Co.

    The SHR-ALV can guide driversin whole darkness. With inhibitory function of strong light, it can assist drivers to see the road and the surrounding circumstances when a head-on dazzling light emerge.It can be united with Risk Detector System in order to sound the alarm when face the obstacle on the road or potential pileup. Under special circumstances, the drivers couldturn off the lights andtake a covert moving rely on Night-Vision system. And the quality is reliable, connection is convenient.

  • Calibrated Reflectance Panel

    MicaSense, Inc.

    Using the (Calibrated Reflectance Panel (CRP) in conjunction with MicaSense RedEdge-M and Parrot Sequoia cameras enables more accurate compensation for incident light conditions and generation of quantitative data. The CRP has known reflectance values across the visible and near-infrared light spectrum. As a best practice, CRP images should be captured before and after each flight to provide an accurate representation of light conditions during the flight.

    Moving Detector Goniophotometer completely meets LM-79 Clause 9.3.1 and EN13032-1 clause goniophotometer type 4 requirements. The LSG-5000 is an automatic light distribution intensity 3D curve testing system for measuring light. The measuring distance is from 5m to 30m. It can measure all types of lighting sources, LED or HID luminaires such as indoor and outdoor luminaires, roadway luminaires, street lamps, flood lights and other kinds of luminaires.

  • DB-9 PockeTester™

    Model 51 - Patton Electronics Co.

    The Patton Model 51 DB-9 PockeTester™ monitors the seven most important async EIA-574 (RS-232 on a DB-9) data and control lines. The Model 51 uses seven tri-state LEDs to indicate the presence of the following signals: TD, RD, DTR, DSR, RTS, CTS and DCD. A red light = Mark, a green light = Space and no light indicates no signal on the line. No AC power or batteries required..

  • Electrical Testers

    Curt Manufacturing

    Part of towing responsibly is making sure your trailer lights are working properly. Whether you have just installed a new vehicle-to-trailer wiring harness or are trying to locate the cause of an electrical problem, CURT connector testers are great for testing tail lights, turn signals, brake lights, ground connections and other electrical components on your trailer.

  • Digital Illumination Meter

    Shenzhen UYIGAO Electronic Technology Co., Ltd

    Is a device used to measure the amount of light. In photography, a light meter is often used to determine the proper exposure for a photograph. Typically a light meter will include either digital or analog electronic circuit, which allows the photographer to determine which shutter speed and f-number should be selected for an optimum exposure, given a certain lighting situation and film speed.

  • Highly Collimated Solar Simulators

    Sciencetech, Inc.

    This solar simulator is based on a Fresnel lens to collimate the light beam from the arc lamp source to infinity, which results in highly collimated illumination of the target spot. A 2.5kW xenon ozone free lamp is used as the light source. The spectral distribution of the xenon light source, along with the use of specially calibrated AirMass filters, closely simulates the sun’s true spectral distribution in various conditions on Earth.

  • Flash Parallel Solar Simulator

    All Real Technology Co. Ltd.

    All-Real Flash Parallel Solar Simulator - HCPV module tests comprises three major parts of flash light source, HCPV module power rating station and IV Tracer. Light Source and collimated mirror: The collimated angle of radiation is within ± 0.5° very similar to the real sun (with a controlled reference spectrum similar to AM 1.5D) to well simulate natural sun light and leads to accurate measurement. IV Tracer:

  • Fork Sensors

    SICK Sensor Intelligence

    Fork sensors, which operate using a through-beam design, combine the sender and receiver in a single housing. As a result, alignment is no longer time-consuming. Even very slight differences in light attenuation are detected due to highly focused light emission and high detection accuracy. Easy installation, high immunity to ambient light, and a wide range of fork widths are some of the many advantages that SICK fork sensors offer. Applications include detecting labels or parts on conveyors.
