    摘要: A method of making an optical assembly includes obtaining a first optical element having a first optical surface and a second optical surface that is opposite to the first optical surface, and a second optical element having a third optical surface and a fourth optical surface that is opposite to the third optical surface. The second optical element is distinct and separate from the first optical element. The method also includes obtaining an enclosure configured to enclose the first optical element and the second optical element. The method further includes providing one or more fillers in the enclosure so that the one or more fillers are in contact with the second optical surface and the third optical surface, thereby making the optical assembly. Also disclosed are an optical assembly made by the method and an optical imaging device including the optical assembly.

    摘要: A method for making a hybrid lens includes providing, in a mold having a first Fresnel pattern, (i) a first lens and (ii) a silicone material comprising silicone and curing the silicone material in the mold to form a hybrid Fresnel lens. The cured silicone material is mechanically coupled with the first lens; and the cured silicone material has a second Fresnel pattern that corresponds to the first Fresnel pattern. A hybrid lens made by this method is also described. A hybrid lens includes a first lens mechanically coupled with a cured silicone material. The cured silicone material has a Fresnel pattern on a surface that faces away from the first lens.
