<p><P>PROBLEM TO BE SOLVED: To provide an optical element that reduces the distortion during coupling when the optical element is manufactured by coupling at least three optical elements sandwiched between a resin layer and an optical component, and has high environmental resistance, a high optical characteristic, and a color aberration correcting effect. <P>SOLUTION: This optical element is formed by coupling the second optical component to a resin layer molded on one surface of the light incoming/outgoing surfaces of the first optical element using an adhesive. When the outer diameter of the resin isϕr and the effective part diameter of the surface of the second optical component coupling to the resin layer isϕg, the optical element establishes the condition ofϕg<ϕr. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
