    OptCom Co., Ltd

    O-E probe is the unit to convert optical signals to electrical signals. It can be connected to Oscilloscopes or data loggers via a BNC connector and monitor the conversion waveform. It can acquire the optical signal easily by just pointing the optical fiber probe at the light source. Recently, more and more light sources utilize optical modulation for next generation lighting such as LED. Acquiring the emission timing is required to measure the emission phenomenon of the light source. This O-E probe unit is the ideal tool for these tasks.

  • Leakage Measurement Instrument


    The instrument is designed to produce a low current, high voltage which is applied to the motor winding. The circuit includes means for measuring leakage currents and for triggering alarms for selected levels of leakage. These alarms may be the existing high level alarm light and horn, or can be wired into the telemetering terminal board. The AUTOMEG/SUBMEG module includes a green sunlight visible LED display light to indicate power and a red sunlight visible LED display light to indicate one (1) megohm motor winding leakage resistance to ground.

  • Optical Camera Trigger

    Ophir Photonics

    The Optical Camera Trigger is an optical sensor that detects pulsed light sources and generates outputs to trigger a camera. The front aperture of the Optical Trigger must be directed at a light source that provides the necessary properties for trigger activation. (e.g. a laser flash lamp, a pick-off source from the main laser beam, or similar). The light source may be a direct or indirect pulsed waveform.

  • Reflectance/Transmittance Test Set

    RT-500 - Lumetronics

    An Integrating Sphere is a hollow sphere which has its interior coated with a paint that is nearly perfectly diffuse or Lambertian and which has extremely high reflectance. Light energy introduced in an integrating sphere is reflected from the wall and distributed uniformly around the interior. A detector which is placed at a hole or 'Port' in the sphere wall sees an output which is completely independent of the angularproperties of the input light. The independence of the output of a sphere from the angular properties of the input and the uniform internal distribution of light make integrating spheres ideal for many uses.
