  • All LED Solar Simulator Spectrally Tunable Class AAA Sun Simulator

    LEDSim - Aescusoft GmbH

    Long LED lifetime (min 30,000 hours) leads to increase in equipment uptime and reduced maintenance and consumables costs. IV-testing of solar cells under variable irradiation. Full characterization of spectral matching of multi-junction devices. Little heating of solar cell during measurement due to cold LED light, allows for longer light pulses up to DC operation without active cell cooling.

  • 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.

  • Detectors

    Edmund Optics Inc.

    Detectors are used to measure the illumination of a light source for a number of optical or spectrometry applications. Detectors consist of arrays of photodiodes or photodetectors that transmit electrical current when excited by collision from photons. Detectors enable the measurement of important light characteristics that are not conveniently acquired in other ways. A selection of photodiodes is also available with linked amplifier capabilities for easier, more precise measurement capacities.Detectors

  • Data Loggers

    UX90 Series - Onset Computer Corporation

    The HOBO Occupancy & Light data logger monitors room occupancy and indoor light changes to identify occupancy patterns and determine energy usage and potential savings. The HOBO UX90-006 Room Occupancy/Light Data Logger is available in a standard 128 KB memory model (UX90-006) capable of 84,650 measurements and an expanded 512KB memory version (UX90-006M) capable of over 346,795 measurements.

  • 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.

  • DELAY PULSE GENERATOR

    DPG 5000 - Hinds Instruments, Inc.

    The PEM is a resonant device that cycles through polarization states in 15-25 microseconds (for an I/FS50 the frequency is nominally 50 kHz, the period 20µs). For a given device, this frequency and period cannot change. A continuous light source will have its polarization modulated at the PEM frequency. However, a pulsed light source will require timing compatibility such as that provided by the Delay Pulse Generator to synchronize with a PEM in a polarization application set up.

  • Femtosecond Streak Camera

    FESCA-100 - Hamamatsu Photonics K.K.

    The FESCA-100 can measure optical phenomena in 100 femtoseconds (one-quadrillionth of a second) with a temporal resolution twice as high as conventional products. The FESCA-100 was developed for applications including the tuning of accelerators, where the measurement of light emission phenomena occurs in extremely short time periods by irradiating an accelerated block of electrons to a metal plate. Simultaneous measurement of light intensity and spatial (wavelength) axis.

  • FIber Based Solar Simulator

    Sciencetech, Inc.

    Provides up to 12 suns class B non-uniformity over a 12.5 mm diameter with the A4 Light Line and class C uniformity can be achieved over 18mm diameter both with a working distance of 25 cm. Provides up to 4 suns class B non-uniformity over a 12.5 mm diameter with the A1 Light Line with a working distance of 25 cm.

  • 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.

  • 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.

  • Microscope Detection Unit

    Biophotonics Solutions Inc.

    The Microscope Detection Unit (MDU) is designed to facilitate femtosecond pulse compression and measurement directly at the focal plane of a microscope, inverted or upright. It contains a nonlinear crystal for second harmonic generation (SHG) as well as other optical elements to separate SHG photons from the laser light and to couple the SHG light into a compact spectrometer via SMA-connected fiber.

  • 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.

  • 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.

  • 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.
