High sensitive detector head for the measurement of photopic illuminance in Lux [lx]. Features: f1 ≤ 3 %, 2.8nA/lx, 20mm diffuser, for the usage with optometers and amplifiers, calibration certificate
The PD-9310A is an illuminance measurement head with a 1cm² large photodiode ensuring high illuminance responsivity. Its minimal noise equivalent signal (about 36µlx) makes it specifically ideal for measurement of low illuminance levels. Its photometric responsivity corresponds to the DIN-5032 - Article 7 quality class A. The large diffuser window offers an approximated cosine field of view function. The detector can be combined with all optometers and light meters from Gigahertz-Optik.
The PD-9310A is calibrated in terms of its absolute illuminance responsivity and relative spectral responsivity by the Gigahertz-Optik calibration laboratory for optical radiation measurands. The calibrations are documented in an individually compiled calibration certificate. The design and contents of the calibration certificate are in accordance with the ISO 17025 specifications.
