Go back to LED Test overview

- Duplex and Trident fiber-optic probes are available in small-aperture sizes only and provide the sequential test of 2 or 3 LEDs (the LEDs must be turned on one-at-a-time) .
- Wide-aperture fiber-optic probes allow 4x the amount of light input as small-aperture fiber-optic probes and are recommended for the test of dim LEDs, or mis-aligned LEDs.
- Contacting fiber-optic probe tips are recommended for more refined intensity measurement as they ensure a consistent distance between the fiber-optic probe tip and the LED under test.
