Abstract
In a method of fixing an optical member for fixing the optical member to a supporting member, an intermediate member that is fused upon irradiation light is disposed between the optical member and the supporting member. By irradiating the light that is transmitted through the optical member onto the intermediate member, the intermediate member is fused, and the optical member is fixed to the supporting member.

A method of fixing an optical member for fixing a second lens to a first lens, the method comprising:
- a) a step of disposing an intermediate member that is fused by being irradiated the light between the first lens and the second lens;
- b) a step of adjusting a position of the second lens with respect to the first lens;
- and
- c) a step of irradiating the light that is transmitted through one of the first lens and the second lens onto the intermediate member disposed between the first lens and the second lens, whereby the intermediate member is fused to fix the second lens to the first lens.
A method of fixing an optical member for fixing a second lens to a first lens, the method comprising:
- a) a step of disposing an intermediate member that is thermo-fused by being irradiated a laser beam between the first lens and the second lens;
- b) a step of adjusting a position of the second lens with respect to the first lens;
- and
- c) a step of irradiating the laser beam that is transmitted through one of the first lens and the second lens onto the intermediate member that is disposed between the first lens and the second lens, whereby the intermediate member is thermo-fused to fix the second lens to the first lens.
An optical unit comprising:
- a) a first lens;
- b) a second lens;
- and
- c) an intermediate member that is disposed between the first lens and the second lens and is fused by being irradiated the light that is transmitted through one of the first lens and the second lens, wherein
- the first lens and the second lens are fixed by the intermediate member.
An optical unit comprising:
- a) a first lens;
- b) a second lens;
- and
- c) an intermediate member that is disposed between the first lens and the second lens and is thermo-fused by being irradiated a laser beam that is transmitted through one of the first lens and the second lens, wherein
- the first lens and the second lens are fixed by the intermediate member.
