  • 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.

  • 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.

  • 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.

With featuers of durable structure, large LCD display with backlight and friendly operation interface, the 3108 advanced stability handheld optical light source provides a lot of convenience for your field work. High stability of output power and quite stable output wavelength, it is an ideal instrument for optical network installation, trouble shooting, maintenance and other optical fiber related systems.

  • Airborne Thermal Imaging System

    Star SAFIRE 380-HLDc - FLIR Systems, Inc.

    Introducing the Star SAFIRE 380-HLDc compact, high-definition, multisensor targeting system designed specifically for use on light rotorwing aircraft. The 380-HLDc provides an unmatched "SWaP-T" advantage – Size, Weight and Power plus true Targeting capabilities – in a sensor package tailored to give light attack helicopters the uncompromising Intelligence, Surveillance, Reconnaissance and Targeting (ISR&T) performance required to locate, identify, and engage targets at maximum range.

  • 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”

  • Optical microscopy (OM)

    Materials Analysis Technology Inc.

    Optical microscopy is used to display the surface morphology of samples by 2D intensity contrast due to deflection and reflection of visible light shined on areas of interest. Its resolution is about half of the incident wavelength, which is ~0.2 μm for visible light (wavelength of 400-700 nm). Such resolution limits the maximum magnification to X1000, and thus optical microscopy provides preliminary inspection of sample surface structure.

  • 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.

  • Laser Photodiode Sensors

    Ophir Photonics

    Photodiode sensors have a high degree of linearity over a large range of light power levels: from fractions of a nanowatt to about 2 mW. Above that light level, corresponding to a current of about 1 mA, the sensor saturates and reads erroneously low. Therefore, most Ophir PD sensors have a built-in and removable attenuator allows measurement of up to 3 W without saturation.
