  • 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.

  • Red and Infrared (IR) Dual Wavelength Laser Diodes

    Panasonic Electric Works Corporation

    Panasonic's Red and Infrared (IR) Dual Wavelength Laser Diode is a dual-wavelength laser that outputs both red and infrared laser lights.  The Laser Diode is a single chip integrating two laser chips and uses high-accuracy light emission point control, low-profile package, and other advanced technologies, thus allowing to improve the productivity of products and the margin in their optical design and to make them thinner.

  • 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.

  • Cloud Height Instruments

    Bristol Industrial & Research Associates Ltd

    Ceilometers are stand-alone instruments designed to measure cloud and aerosol height profiles using a laser based LIDAR (Light Detection And Ranging) technique. The light emitting component is a low power diode laser with the output power limited to an eye-safe level. They determine cloud base heights, penetration depths, mixing layer height and vertical visibilities. Within their operating range they reliably detect multiple cloud layers and cirrus clouds.

  • Cable Tester

    PA-03/03SR STP - Pansco, Ltd

    The STP cable tester offers a simple-to-use, no-buttons test for shielded and unshielded twisted pair cables such as T568 A/B and 10/100 Base-T. It evaluates cables immediately upon plug-in, displaying continuity, opens, and shorts on its easy-to-read LED display. Dual color LED determines whether cable is properly wired for data use, with straight-through pinning (lights up green), or for voice communication, with cross-pinning (lights up red).

  • Camera Uniformity Test - KT Mini Sphere

    Konrad Technologies GmbH

    The KT Mini Sphere is a uniform light source and integral intensity detector based on the integrated sphere concept. Combined with precise current amps and photodiodes for internal adjustment it is capable of accurate intensity and color correlated temperature (CCT) control. The KT-Mini-Sphere can also reperesent light with different intensities. With our calibration and adjustment procedure we are able to allow nearly step less dimming (16bit resolution of current amps) as well as calibrations for different CCTs.

  • Battery Data Logging Device

    FST-AM - Foresight Electronics Co., Ltd.

    A data logger, is an electronic instrument that records measurements at set intervals over a period of time. Depending on the particular data logger, measurements can include: air temperature, relative humidity, AC/DC current and voltage, differential pressure, time-of-use (lights, motors, etc.), light intensity, water temperature, water level, dissolved oxygen, soil moisture, rainfall, wind speed and direction, leaf wetness, pulse signals, room occupancy, plug load, and many more.

  • Photometric converter

    HC 4000 - optek-Danulat GmbH

    The Haze Control 4000 photometric converter is designed to operate with the optek DTF16 (11°/90° scattered light sensor) and additionally with AF16 or AS16, visable (VIS) or near-infrared (NIR) based sensors. The graphic display can show absorbance, turbidity and concentration in real-time and in any unit of measure such as EBC, FTU, ppm (DE), NTU, ASBC and Helms. These measurements may also be displayed as text, bar graphs or trend values. A factory zero point is implemented for the scattered light sensors.

  • Photonic Hall Effect

    HMS7000 - ECOPIA

    Classic hall effect measurement system is to read voltage difference made between both diagonal sides, when flowing current and applying magnet field strength, in perpendicular to flowing current direction. - Photonic hall effect measurement is to read various electrical properties by illuminating light of “various range of wavelength” on the sample, in addition to flowing current and applying magnet field strength. - It is great to see “RGB (Red, Green, Blue), Light intensity vs carrier density, carrier mobility, resistivity, hall coefficient”

  • 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.

  • Portable and Automatic Mini-Distillation Analyzer

    MINIDIS ADXpert Automatic Mini-Distillation - Grabner Instruments

    This true atmospheric distillation analyzer is extremely compact, portable and light weight and operates as a fully stand-alone unit. Designed for the quick and accurate quality control in laboratories and in the field, a distillation run on light products takes just 15 minutes and requires as little as 6 mL of sample. Because of its small size, the portable mini-distillation apparatus is the ultimate solution for places where limited or no lab-space is available.

  • Microscope Cameras

    Carl Zeiss AG

    In contrast to digital cameras for normal photography, microscope cameras are built to meet the demands of high-end science- and research applications. For maximum light sensitivity they use large CCD or CMOS sensors for image acquisition. Color reproduction is often critical, why features like Microscanning or Color-Co-Site Sampling ensure optimal image quality. Due to the lack of a light absorbing color filter monochrome microscope cameras for fluorescence imaging are even more sensitive.

  • Spectroscopy

    Edmund Optics Inc.

    Spectrometers are used to measure the properties of light for a variety of applications including environmental or chemical analysis, fluorescence, or Raman. Spectrometers are optical instruments that can detect spectral lines and measure their wavelength or intensity. Spectrometers are ideal for determining compositional makeup for detecting weak light signals. Spectrometers can also be used to test the efficiency of an optical filter in order to determine whether a filter has properly blocked or transmitted specific wavelengths.

  • 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.
