Abstract

Methods, systems, devices, and apparatuses are described. Light output by a light source may be transformed into an annular shape (e.g., a spatial distribution of the light may be modified to have an annular shape) to cure an adhesive material having a similar annular shape. For example, a system may include a light source emitting light (e.g., ultraviolet (UV) light) having an angular distribution and a spatial distribution. An optical system may modify a shape of the spatial distribution into an annular shape, and the light having the annular shape may be focused on an adhesive material to cure the adhesive material. In some examples, the adhesive material may be positioned between an optical element and a structural component, and the focused light in the annular shape may cure the adhesive material while simultaneously avoiding one or more other optical components or structures.
