Adhesion Method

Lens to PCB (3)4. MechanicalFastener

LED to Lens / Lens to LED (1, 2)Secure a plate with a hole of ~5% larger diameter than the lens optic, fitted over the lensCare must be taken to ensure no scraping or other physical damage to the lens optic when mounting

Securing Plate
This method allows easier lens replacement
while preserving the LED, where desired

Wavelength [nm]Summary
1.

From ~320nm boundary, transmittance decreases in shorter wavelengths, yet increases in longer wavelengths.

2.

UV irradiation clearly causes a change in the optical qualities of the material; whether this can be considered degradation orlong-duration curing of a sort depends on one’s viewpoint.

3.

The material can be considered highly UV-durable at a reference wavelength of 365nm.
