Abstract
An optical system includes a lens assembly and a light source. The lens assembly includes an optical lens positioned to transmit and refract light provided by the light source, and a lens holder coupled to the optical lens and maintaining a position of the optical lens relative to the light source. The optical lens is coupled to the lens holder with a bonding agent arranged in an interrupted configuration at positions proximate to a circumference of the optical lens. The light source provides light to the optical lens of the lens assembly that has an optical footprint that includes a plurality of high-intensity regions separated from one another by low-intensity regions and the bonding agent is positioned in a circumferential orientation relative to the light source such that the bonding agent is spaced apart from the high-intensity regions of the optical footprint of the light.
