1. A system comprising:
a light detection and ranging (LIDAR) sensor including a lens through which light is transmitted and received, the lens having an outer surface; and
an applique that is adhered to the outer surface of the lens, the applique comprising:
a transparent sheet having:
a first surface; and
a second surface that is opposite the first surface; and
a ultraviolet (UV) curable pressure sensitive adhesive that is disposed on the first surface of the transparent sheet, that is curable using UV light, and that is configured to adhere the transparent sheet to the outer surface of the lens,
wherein, prior to application of the UV curable pressure sensitive adhesive to the transparent sheet, the first surface of the transparent sheet is treated by an ozone treatment process,
wherein the lens exhibits a first index of refraction;
wherein the UV curable pressure sensitive adhesive exhibits a second index of refraction after being UV cured;
wherein the transparent sheet exhibits a third index of refraction;
wherein the third index of refraction of the transparent sheet is less than the second index of refraction of the UV curable pressure sensitive adhesive; and
wherein the second index of refraction of the UV curable pressure sensitive adhesive is less than the first index of refraction of the lens.
