Abstract
A lens module including a first unit including a first lens and a first holder made of a material different from a material of the first lens and configured to hold the first lens and a second unit including a second lens and a second holder made of a material different from a material of the second lens and configured to hold the second lens. The first lens and the second lens overlap in an optical axis direction of the lens module, and the first holder and the second holder fit with each other.
Claims30
A lens module comprising:
- a first unit including a first lens made of a first material and a first holder made of a second material different from the first material and configured to hold the first lens;
- and
- a second unit including a second lens and a second holder made of a material different from a material of the second lens and configured to hold the second lens, wherein
- the first material is a resin material which is an acrylic resin or a cyclic olefin polymer, or a glass material, and
- the first lens and the second lens overlap in an optical axis direction of the lens module, and the first holder and the second holder fit with each other.
A lens module comprising:
- a first unit including a first lens made of a first material and a first holder made of a second material different from the first material and configured to hold the first lens;
- and
- a second unit including a second lens and a second holder made of a material different from a material of the second lens and configured to hold the second lens, wherein
- a coefficient of linear expansion of the first material is 1/5 times or larger and five times or smaller of a coefficient of linear expansion of the second material, and
- the first lens and the second lens overlap in an optical axis direction of the lens module, and the first holder and the second holder fit with each other.
A lens module comprising:
- a first unit including a first lens made of a first material and a first holder made of a second material different from the first material and configured to hold the first lens;
- and
- a second unit including a second lens and a second holder made of a material different from a material of the second lens and configured to hold the second lens, wherein
- the second material is an amorphous resin, and
- the first lens and the second lens overlap in an optical axis direction of the lens module, and the first holder and the second holder fit with each other.
A manufacturing method for a unit including a lens and a holder that holds the lens, the manufacturing method comprising installing the holder in a die and feeding a cyclic olefin polymer or an acrylic resin into the die to insert-mold the lens into the holder.
