Lens Assembly Instructions

Lens holders can be assembled to the PCB using an epoxy or polyurethane-based adhesive (example: Dow

Corning 3145 RTV).

Cyanoacrylate (superglue) adhesive should not be used to avoid contamination of the lens (blooming of the epoxy).

When integrating the lens into a fixture without the lens holder, special attention is needed to maintain the distance

between the lens bottom and the emitter top. Variation in this distance will result in variation of the beam profile.

See mechanical detail B. on previous page.

Lens Cleaning

For the removal of dust, use a lint-free soft cloth.

For the removal of stains, use a neutral detergent, i.e. dishwashing soap.

Do not use any solvents, abrasive liquids or abrasive fabrics because they may damage the optical grade lens

surfaces.
