  • Stroboscopes

    Lutron Electronic Enterprise Co., Ltd.

    Is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary. It consists of either a rotating disk with slots or holes or a lamp such as a flashtube which produces brief repetitive flashes of light.

  • Lux Meters

    Rinch Industrial Co.,Limited

    Lux meter is used for measuring illuminances in work places.The lux is the SI unit of illuminance and luminous emittance. It is used in photometry as a measure of the apparent intensity of light hitting or passing through a surface.

  • Fiber Optic Sensors

    Tri-Tronics Company Inc.

    Fiber optic sensors are a special type of sensor that uses fiber optic light guides to deliver the light to the sensing position. They work well for applications involving small targets, unfavorable conditions and tight areas. Glass fibers can be used in harsh environments without damage and are more rugged than plastic fiber optics. Plastic fiber optics are more flexible and cost-effective and can be cut to length. When applied correctly, fiber optic sensors solve many applications general purpose sensors can't solve.

  • Fiber Visualizer

    Norland Products, Inc.

    The Norland Fiber Visualizer is a unique instrument which simplifies installation and testing of fiber optic networks. This compact unit uses a 0.5 mW helium neon laser, with an ultra-precision optical adapter, to focus high intensity visible light into the core of a fiber optic connector. As the light travels down the fiber, a visible red glow is emitted anywhere discontinuity occurs. The Visualizer imitates on the visible level, what normally occurs in the invisible infrared spectrum,thereby allowing the end user to actually see any problems in the system.

  • Inductively Coupled Plasma Spectroscopy (ICP-OES/MS), ICP Analysis Services

    Evans Analytical Group®

    ICP-OES measures the light emitted at element-specific characteristic wavelengths from thermally excited analyte ions . This light emitted is separated and measured in a spectrometer, yielding an intensity measurement that can be converted to an elemental concentration by comparison with calibration standards. ICP-MS (ICP-Mass Spec) measures the masses of the element ions generated by the high temperature argon plasma. The ions created in the plasma are separated by their mass to charge ratios, enabling the identifcation and quantitation of unknown materials. ICP-MS offers extremely high sensitivity (i.e. low detection limits) for a wide range of elements

  • LED Analyser

    Feasa - Intrinsic Quality,Inc

    Each LED Analyser allows for simultaneous measurement of up to 20 different light sources as it measures Color and Intensity – Brightness Test. Light from the LEDs is transferred by Plastic Optical Fibers and transported to the LED Analyser board for accurate measurement and analysis. The Feasa Analyser has been engineered to test LED’s and other lighting devices such as LCD Displays automatically. Intrinsic Quality offers a LED tester demo unit that can be tried out for two weeks free of charge. Currently available for purchase, call to order:

  • LED tester

    ECOPIA

    Ecopia's LED tester is good to measure both electrical(I-V curve) and optical(Spectra, Light intensity) properties of LED chip, LED lamp, SMD type at the same time.It also makes it possible to see LED sample's construction , seeing through microscope. LED tester main body flow input current ,and emitted light from the LED sample is focused on lens of microscope.From this process, our LED tester can provide repeatable tested results and minimize error values and improve convenience of how to use.

  • Luminance Meters

    Metrue Inc.

    Luminance meter utilizes a CCD in order to take the luminance of every pixel in an image. It is perfect for applications in which the luminance to be measured will vary greatly and in which multiple points must be taken or in which the zonal luminance and total average luminance is important. Image luminance meters can also be used in glare measurement, LEDs, automotive lights, traffic lights, indicator lamps, instrument and equipment panels, landscape and street lighting, biological luminescence, and any sort of display including LED, plasma, OLED, and any backlight panel.

  • MPO/MTP Multi-Fiber Interferometer

    Anfkom International Co.,Limited

    It is an automatic and non contact fiber endface interferometer for both multi fiber and single fiber connectors. It can measure the geometry parameters of multi fiber connector such as fiber height,core dip, X and Y angel, radius of curvature with white light and measure geometry parameters of single fiber connector with red light. The software can display the surface of the connector in 3D image for a very short time, it need only 8s to test 12-core MT connector. It is intelligent , efficient,stable and accurate and very helpful in improving the quality of the product.

  • Solar Simulation

    Sciencetech, Inc.

    Sciencetech solar simulators produce high intensity, uniform illumination on a target area. Typically, high power solar simulators use an ellipsoidal reflector to capture light from an arc lamp source inside the reflector, an arrangement that results in a light pattern with a bright outer region and a dark center. This non-uniformity is un- acceptable in many solar simulator applications and as a result, forces many of our solar simulator competitors to use designs involving diffusers to reduce the non-uniformity. This results in a reduction of intensity and a dis- tortion of the spectrum on the target area.

  • Ultra-High Resolution Spectrometers

    Is-Instruments

    Fabry-Pérot interferometers are optical resonators used for high-resolution spectroscopy. They use the phenomenon of multiple-beam interference that results when light shines through a cavity bounded by two reflective parallel surfaces. When the light hits one of the surfaces, some is transmitted out, and the remaining part is reflected back. Fabry-Pérot produces a circular fringe pattern, similar to the Michelson pattern. However, the fringes are thinning, brighter, and more widely spaced. As a result, these instruments are able to detect and resolve the fine features of a transmission spectrum with high precision.

  • Variable Fiber Optic Attenuator

    Huihong Fiber Inc

    Variable fiber optic attenuator could help simulate distance or actual attenuation in the fiber optic testing work by inserting a calibrated attenuation into the link. By using the variable fiber optic attenuator, technicians could verify the power margin received by testing the fiber optic link power budget. Variable fiber attenuator can help user vary the light power injected from a light source into the optical fiber. Important parameter of variable fiber attenuator include its insertion loss, reflection loss and attenuation range.
