Claim:
1. An optical system comprising: a light source and a lens assembly, the lens assembly, comprising: 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 coupled to the lens holder with a bonding agent arranged in an interrupted configuration at positions proximate to a circumference of the optical lens such that the lens assembly comprises a gap between the lens holder and the optical lens, wherein the light source provides light to the optical lens of the lens assembly, wherein the light provided to the optical lens has an optical footprint that includes a plurality of high-intensity regions separated from one another by low-intensity regions; wherein the intensity of the light evaluated around the circumference of the optical lens approximates a step function; wherein the intensity of the light in the low-intensity regions of the step function is less than about 50% of the maximum intensity of the light in the high-intensity regions of the step function; and wherein 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.
