How to choose your holder?

The right lens holder is the key

Reading time : 5 minutes
Last update : may, 2023

Achieving an optimal focus position of the lens is the key factor for a successful LED/Collimator integration. Different holder references are available to position collimators to considered LED. PCB to LES height: the Light Emitting Surface (LES) position must be known and is specific to each LED. It can be found on LED manufacturer datasheet. Here below are 2 examples with and without dome.
Correct position is achieved when PCB to LES height from datasheet is equal or close
to the PCB to LES of this document.
Exemple:

DISTANCE FROM PCB SURFACE TO FOCUS POINT OF OPTIC
