LENS MODULE FOR IMAGING APPARATUS

摘要

A lens module for an imaging apparatus includes a lens assembly including a first lens and a second lens, a holder holding the lens assembly, a first adhesive that adheres the first lens to the holder, an elastic modulus of the first adhesive being larger than an elastic modulus of the first lens, and a second adhesive that adheres the first lens to the holder, an elastic modulus of the second adhesive being smaller than the elastic modulus of the first lens. The first adhesive is interposed between one surface of the first lens and the holder and the second adhesive is interposed between the other surface of the first lens and the holder.

1. A lens module for an imaging apparatus comprising:
a lens assembly including a first lens and a second lens; a holder holding the lens assembly; a first adhesive that adheres the first lens to the holder, an elastic modulus of the first adhesive being larger than an elastic modulus of the first lens; and a second adhesive that adheres the first lens to the holder, an elastic modulus of the second adhesive being smaller than the elastic modulus of the first lens; wherein the first adhesive is interposed between one surface of the first lens and the holder and the second adhesive is interposed between the other surface of the first lens and the holder, such that effect of a change of refractive indices of the first and second lenses due to change of temperature of the lens assembly on a focal length of the lens assembly and effect of deformation of the first lens due to the change of the temperature of the lens assembly on the focal length of the lens assembly cancel with each other.
