  • Notes

  • Tektronix Irradiance Probe J6502 for Tektronix Photometer/Radiometer J16 measures irradiance in microwatts/cm2 (milliwatts/m2 with Option 02).
    The spectral response is flat from 450 to 950 nanometers, ±7%. The response is typically down 50% at 400 and 1030 nm.
    An optional filter holder is available for the J6502 to mount standard 1 inch diameter customer-supplied filters of up to 3/8 inch thickness. Where high intensity sources are used (over 1990 µwatts/cm2), neutral density filters can be used to extend the range of the J16. (An ND 1 filter has 10% transmission, an ND 2 1%, etc.). These filters may be held with an optional filter holder. Where the 1 sq cm sensor is not completely filled by the source, for example with a laser beam, the reading obtained represents microwatts instead of µwatts/cm2 or milliwatts x10-4 instead of milliwatts/m2 (Option 02). Small variations in sensor uniformity may add ±5% uncertainty to this measurement.
