Abstract
An optical function module comprises a collimator block having a substrate, at least two collimators disposed on the substrate in confronting relation to one another for collimating a light flux directed along a preselected path between the collimators, and support members each for supporting a respective one of the collimators on the substrate. An optical function device is removably connected by a connecting structure to the collimator block so that the optical function device is positioned along the preselected path of the light flux between the collimators.
Claims28
An optical function module comprising:
- a collimator block having a substrate, at least two collimators disposed on the substrate in confronting relation to one another for collimating a light flux directed along a preselected path between the collimators, and a plurality of support members each for supporting a respective one of the collimators on the substrate;
- an optical function device positionable along the preselected path of the light flux between the collimators of the collimator block;
- and
- connecting means for removably connecting the optical function device to the collimator block.
An optical function module comprising:
- a substrate having a main surface and a recess formed in the main surface;
- at least two collimators mounted on the main surface of the substrate in confronting relation to one another for collimating a light flux directed along a preselected path between the collimators;
- and
- an optical function unit having a base member removably connected in recess of the substrate and an optical function device removably supported by the base member so that the optical functional device is disposed in the preselected path of the light flux between the collimators.
An optical function module comprising:
- an optical function unit having a base member and an optical function device removably connected to the base member;
- and a collimator block having a substrate, at least one pair of collimators mounted on the substrate in confronting relation to one another, and a recess formed in a main surface of the substrate for receiving the base member of the optical function unit so that the optical function device is disposed between the collimators.
