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.

Use 

internal

 spacers to decrease the distance

between LED and lens.

Use 

external

 spacers to offset the mechanical support,

pushing the lens away from the LED.

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.
