  • Visual Fault Locators


    Fiber visual fault locator is a kind of device which is able to locate the breakpoint, bending or cracking of the fiber glass. It can also locate the fault of OTDR dead zone and make fiber identification from one end to the other end. Designed with a FC,SC,ST universal adapter, this fiber testing red light is used without any other type of additional adapters, it can locates fault up to 10km in fiber cable, with compact in size, light in weight, red laser output.

  • Vibration Analyzers/Balancers

    Balmac Inc.

    Vibration Analyzer with Strobe Light for vibration analysis and in-place dynamic balancing. These instruments are known for their rugged durability, reliable operation and accurate readings. The Tunable Filter and Strobe Light are a favorite with operators - easy to use and more convenient than digital filters and laser photo tachs. These analyzer/balancers allow operators to dynamically balance rotors of any size and shape.

  • Uncooled InAsSb Photovoltaic Detector

    P13894-011MA - Hamamatsu Photonics K.K.

    Hamamatsu Photonics K.K. has developed an uncooled InAsSb (indium arsenide antimonide) photovoltaic detector that offers high-speed and high-sensitivity detection of infrared light in the 3 to 11 micron wavelength range. This new device (part number: P13894-011MA) extends the upper limit of sensitivity of Hamamatsu’s InAsSb detectors from 8 microns to 11 microns, which will enable users to measure molecules that absorb longer wavelengths of light and thus analyze more compounds with a single device.

  • TwinMate

    L-208 - Sekonic Corporation

    The Sekonic L-208 TwinMate is a palm-sized analog light meter for hand-held incident and reflected ambient light readings. It can also be mounted onto a camera or bracket using the included hot-shoe adapter for quick, camera-positioned reference readings. Though designed primarily for entry-level users, long-time shooters look to the Sekonic L-208 TwinMate as an accurate, easy-to-stow, back-up meter. Owners of rangefinder cameras who desire an incident and reflected meter also appreciate the included shoe mount.

  • Quantum Sensors

    Apogee Instruments, Inc.

    Apogee offers two types of quantum sensors. The Full-spectrum Quantum Sensors feature an improved detector that provides accurate measurements under all light sources, including LEDs, right out of the box. The Original Quantum Sensor is less expensive and great for measuring all light sources except certain LED colors, where post-measurement correction factors need to be applied to achieve accurate readings.

  • Transmittance Dust Measuring Devices

    SICK Sensor Intelligence

    Maintaining a clear sightline even when dust concentrations are highTransmittance dust measuring devices transmit light through the entire duct. With this type of measurement, light attenuation indicates the concentration of dust inside the duct. These measuring devices are specially designed for medium to high dust concentrations and large duct diameters. Consequently, they are equally suited to emission and process monitoring as they are to hall monitoring applications.

  • Radiative Transfer Numerical Model

    HydroLight - Sequoia Scientific, Inc.

    As a data analysis tool: What was the ambient light field when the data were taken?For example, when imaging an underwater object in the daytime, the ambient daylight contributes noise (in this case, path radiance) to the signal of interest (the light propagating from the target to the sensor). HydroLight can compute the ambient daylight field so that it can be subtracted from the total signal received at the sensor to improve the signal-to-noise ratio of the detected signal.

  • Radiometer/Photometer Kit

    AccuMAX™ Series - Spectronics Corp

    Single detector with dual sensors measures both ultraviolet and visible light. Complies with ASTM specifications for MPI and FPI. Specially engineered for NDT applications. The AccuMAX XRP-3000 radiometer/photometer kit uses a dualwavelength UV-A/VIS sensor detector to measure both ultraviolet and visible light. Featuring automatic zeroing, integration and signal hold, the unit provides accurate readouts for UV, visible irradiance or radiance.

  • Radiometers

    Dymax Corporation

    UV Intensity Meters & Visible Intensity Meter for Light Curing Systems. Dymax UV and visible radiometers are simple to operate and allow operators to monitor and document a UV/Visible light curing process. A low UV/Visible intensity measurement signals an operator to replace the bulb, reflector, or lightguide. Radiometers can also be used to confirm that operators are properly shielded from UV/Visible exposure. Degradation of curing bulbs, lightguides, and reflectors can decrease intensity, resulting in incomplete cures.

  • SEM In-lens Detectors

    El-Mul Technologies

    To meet the challenges of in-lens detection we have developed annular, scintillator based SE and BSE detectors. These feature a small through-hole that minimizes dead area and maximizes electron collection efficiency. SNR is increased and distortion is prevented. El-Mul's know-how and production technologies ensure no interference between the detector and the primary beam. Thin light guide design, polish and coating maximize light collection efficiency.

  • Reflective Condenser

    McPherson, Inc.

    Reflective condensing system and focusing accessory for coupling light sources to monochromators. It uses two mirrors to focus to the entrance slit. The reflective system eliminates chromatic aberration, provides maximum spectral range, and does not require refocusing. Accessories like light choppers and filter wheels can also fit inside next to the slit. Versions with rotatable mirror available for up to four source direction.

  • spherical illuminators

    LE6 - Image Engineering GmbH & Co. KG

    The spherical illuminators work on the principle of an integrating sphere. A light source illuminates the interior of a sphere which is coated with a special white diffuse coating. A plane (measuring window) which usually needs to be small compared to the diameter of the sphere and oriented perpendicular to the incident light is illuminated extremely uniform. Due to our internal design the measuring window can be much bigger.

  • Parallel Solar Simulator

    All Real Technology Co. Ltd.

    All-Real developed the first Parallel Solar Simulator in the world with the collimation angle better than 0.4 degrees. It is designed to meet IEC specifications: Spectral match, Non-uniformity and Temporal instability all achieve 3A standards. Radiation spectrum range is from 350nm to 1,700nm, which is better than IEC60904-9 standard 400nm to 1,100 nm. The light source can best replicate real sun light condition.

  • Shearography - Non Destructive Testing (NDT)

    Dantec Dynamics A/S

    Shearography is an optical, Non- Destructive Testing (NDT) technique that provides fast and accurate indications about internal material discontinuities or anomalies in non-homogenous materials. Using laser light, a shearing interferometer is able to detect extremely small (sub-micrometer) changes in surface out-of-plane deformation. When a test object is subjected to an appropriate load, a proportional strain is induced on the test surface. If underlying discontinuities are present, the surface will deform unevenly at these locations. This is then interpreted through the shearing interferometer as a change in the phase of the laser light.
