ABSTRACT:
In order to reduce the light reflectance, an optical element comprises an optical element body formed of an optical crystal or a lens, and glass members with a prescribed refractive index, wherein the glass member is bonded to each of the light incident and emergent surfaces of the element body by an adhesive agent with a prescribed refractive index. The optical element body will not be affected adversely even if it is made of a crystal which is vulnerable to heat.
