OL 15AB
LED Receptor

The OL 15AB LED Receptor is designed specifically for use with the OL 770-LED High-speed LED
Test and Measurement System to make fast, accurate measurements of the intensity of Light Emitting
Diodes (LEDs). The OL 15AB has been designed in accordance with the CIE Publication 127
measurement recommendations for “Averaged LED Intensity.” The geometries of the OL 15AB LED
Receptor meet CIE Standard Conditions A and B for “near-field” conditions. The versatile assembly
easily adapts to either Condition A or Condition B measurements with a single set of parts. It
incorporates unique features such as a fiber/sphere combination that provides uniform spatial
response and eliminates major sources of error.
The OL 15AB is designed and built to provide the correct measurement distance for CIE Standard
Conditions A & B. The distance applies from the tip of the LED to the 1 cm² circular aperture. For
Condition A, the distance is 316 mm and corresponds to a field-of-view solid angle of 0.001 steradian
(sr). For Condition B, this distance is 100 mm, which yields a field-of-view solid angle of 0.01
steradian.
