2.3.1 Spacers selection and placement
The number and type of spacers to place in your LTCLHP varies for each part number,
depending on LED color and lens type (as shown below). When replacing a no more
operational LTSCHP module or LED source, make sure to preserve the same spacers
configuration of your LTCLHP unit. The following table is provided as a reference and lists
the number and thickness of the spacers to be placed in order to correctly configure your
LTCLHP telecentric illuminator.

Please note that the numbers and thicknesses listed are theoretical values and are characterized
by a certain variability: the number of spacers needed to achieve the optimal light homogeneity can
be different from the theoretical value listed. We suggest to start from the values provided and then
iterate until you achieve an homogeneous illumination.

Using spacers to adjust LED axial position
Without spacers
Use internal spacers to decrease the distance
between LED and lens.
x - spacer thickness
Use external spacers to offset the mechanical support,
pushing the lens away from the LED.
