  • Tunable Edge Filters

    Optoplex Corporation

    Tunable edge filter is a customized product. It usually belongs to 2-port optical tunable filter product platform. Instead of using narrow bandpass filter in the 2-port tunable optical filter, the tunable edge filter utilizes a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. Standard Tunable edge filters support C-band or L-band wavelength range.

  • LIV – High-power Laser Diode Testing

    ficonTEC Service GmbH

    An important aspect of the development and manufacture of laser diodes is the so-called laser diode characterization, or laser IV curve. By applying increasing current to the laser diode so it that emits light, the optical output is measured together with the voltage drop across the diode element. The resulting LIV curve reveals important clues about the quality of manufacture and the performance of the laser diode, enabling a pass/fail decision to be met.

  • Goniophotometer


    A goniophotometer is a system to measure the luminous intensity of the source (or illuminance from the source at a given distance) in many different directions from the source. Compared with the sphere method, the goniophotometer method is theoretically free from errors due to differences in intensity distribution of the light source under test. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and luminance distribution of lamps and luminaires.

  • Radiation (EMF, Nuclear, RF)

    Sper Scientific

    Sper Scientific radiation meters measure EMF, Nuclear, and Microwave radiation levels. Whether you are, measuring the RF strength of Wi-Fi and LAN network, or the electromagnetic field emissions from electrical power lines and transmission equipment, computers, HVAC, audio/video, and other electrical appliances. Our meters are small and light enough to go anywhere, yet sensitive enough to detect minuscule amounts of gamma, beta or X-rays.
