Abstract
A lens includes a first optical surface including an optical axis X, and a first cut end surface at an outer circumference of the first optical surface. The first optical surface has a first SWS configured to reduce reflection of light. The first cut end surface has a second SWS configured to reduce reflection of light. A reflectance of the second SWS with respect to light having a predetermined wavelength is higher than the reflectance of the first SWS with respect to the light having the predetermined wavelength.
