  • 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.

  • MRI POWER SUPPLIES

    Carl E. Holmes Company

    MRI Power Supplies are used in MRI Imaging rooms in hospital environment. The lights in the MRI rooms require DC power. If AC power is used, the quality of the MRI imaging process is compromised. These units are ideal for MRI room, where a 60 Hz flicker free light environment is desired. CEHCO offers four models which are shown below.

  • Modular Infinity Microscope

    MIM - Applied Scientific Instrumentation

    ASI Modular Microscope components consist of tube lenses along with adapters and accessories that either are primarily used in the collimated light space or adapters that are to be used on the image side. Collimated light adapters use the 38mm diameter C60-RING system to connect components. Focus-side adapters attached to lens tubes with either a 30mm diameter coupling to the I.D. of the C60-TUBE, or with a 50mm coupling on the O.D. of the lens tube.

  • O/E Converter

    TIA-4000 - Scitec Instruments Ltd

    The TIA-4000 is comprised of a fibre coupled InGaAs APD detector combined with a variable reverse bias voltage network and fast transimpedance amplifier. The output of the unit is brought out to a type K female SMA connector. Light falling on the detector generates a positive-going proportional current. This current, multiplied by the transimpedance produces a voltage that is proportional to the light incident on the detector surface.

  • 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.

  • 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.

  • 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.

  • Sun Simulator

    BXM-SOL7A - Zhuhai Baixin Machinery Co., Ltd.

    BXM SOL7A is a latest model Sun Simulator of IEC class AAA. Can simulate the sunshine to test the parameters of the solar modules. Parameters are saved in database.

  • 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.
