  • Light Meters

    Sper Scientific

    Our light meters are designed for simple and accurate results in an industrial setting. Whether you are checking work spaces, parking lots, or baseball fields for safe levels of lighting or measuring for testing design compliance, a light meter from Sper Scientific will get the job done. Obtain precise UV, FC or Lux measurements, in multiple light measurement ranges. These light meters are designed for use in work spaces, labs, schools, outdoor studies, optics, home inspections, and many others. In addition, you may use these meters to check compliance with ANSI/NFPA 101 (standards for emergency & exit lighting).

  • Light Sources

    Thorlabs, Inc.

    Welcome to Thorlabs; below you will find links to light emitters, sources, and controllers, a subset of our entire line of photonics products. Our light sources are conveniently separated into coherent and incoherent sources. The coherent source category includes laser diodes, laser diode modules, tunable lasers, HeNe lasers, and femtosecond lasers, while the incoherent source link brings you to a selection of LEDs, white light, and broadband SLD sources. The Quantum Electronics category includes optical amplifiers, modulators, and gain elements that are frequently used in research and OEM applications. All of our light sources and optical amplifiers are supported by an extensive line of mounts, sockets, TEC controllers, and current controllers.

  • Light Soaker

    MESO-11 - Greensolar Equipment Manufacturing Ltd.

    The Light Soaker (MESO) is used in photovoltaic production lines for reliability testing. Its purpose is to expose the PV panels with a constant, high intensity light to get it deteriorated. Measuring the time dependent deterioration of the electrical parameters of the PV structure the reliability parameters could be defined.

  • Light source


    Measurement of maximum of 6 points is possible. By use of thee sensor amplifier box, distance between the light receiving inlet and the controller can be extended to 10 meters. Measurement start signals can be independently output by remote control. This is useful for the light source fixtures integrating shutter mechanism.

  • Light Meters


    An instrument for measuring the intensity of light, used chiefly to show the correct exposure when taking a photograph.

    Senko Advanced Components

    Light Source is ideal for field or laboratory testing of optical communication systems at 850 nm / 1300 nm for datacom testing, 1310 nm / 1550 nm / CWDM 1270 nm ~ 1625 nm ( 20 nm spans ) for all WDM testing, as well as 1490 nm for FTTx testing by using interchangeable SFP transceiver modules. Light Source features zero warm up time, superb productivity and has an easy to use, pocketsized and rugged design.

  • Light Source

    pE-300ultra - CoolLED Ltd.

    CoolLED's pE-300ultrais a fluorescence microscopy light source which offers intense, broad-spectrum LED illumination for imaging most common fluorescent stains. Users have access to both microsecond switching via multiple TTL inputs and the ability to mount inline excitation filters. This, when paired with today's high performance multi band filter sets, facilitates imaging traditionally done via a white light source and a filter wheel, with all the benefits of LED.

  • Light Source

    pE-300white - CoolLED Ltd.

    CoolLED's pE-300white offers intense, broad-spectrum LED illumination for imaging most common fluorescent stains. The pE-300white Light Source can be fitted directly to the microscope or specified with a liquid light guide. The system is a mercury-free alternative that is safer, more controllable, and repeatable than conventional high-pressure gas discharge illuminators. Spectral coverage is from the UV (DAPI excitation) to the Red region (Cy5 excitation). The system is perfect for hospital and regular research laboratory environments.
