  • Notes
  • Tektronix Illuminance Probe J6511 is providing a readout in footcandles [lumens/m2 (lux) for the J6511 Option 02].
    A multi-element glass filter and silicon photodiode ensure a close match to the CIE photopic curve (color corrected). The silicon-sensor recovery time is virtually instantaneous; low-light levels can be measured immediately after exposure to bright sunlight.
    The angular response is accurately cosine corrected, simulating an ideal 180° fieldof-view detector. The low-profile probe has a leveling indicator to ensure accurate measurements where a significant proportion of the illumination comes from sources at low angles to the horizon.
    A 25-foot cable between the probe and Photometer/Radiometer J16 allows the user to be out of the field of view while making measurements.

    Where cosine correction is unnecessary, the standard J6501 probe is available with the same photopic correction and units as the J6511. The 6501 can be used to measure green and yellow LEDs.
