Abstract
An optical device is provided which includes a plurality of optical modules and an alignment compensation module. Each optical module includes an optical component fixedly coupled to a relative reference mount. The relative reference mount is configured to attach to a substrate. A plurality of optical modules mount on the substrate to form the optical device. The alignment compensation module removes residual alignment errors of the optical device.

2. An optical alignment compensation module to align a substantially collimated light beam with an initial angular propagation direction along a Z axis comprising:
-
an afocal optical system configured to deviate the angular propagation direction of the light beam when rotated about a Y axis perpendicular to the initial angular propagation (Z axis) direction, the amount of deviation less than the amount of rotation of the afocal optical system; and
a mount configured to rotate the afocal optical system about the Y axis perpendicular to the initial angular propagation direction (Z axis). - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

4. A method of compensating the alignment of an optical system to align a substantially collimated light beam with an initial angular propagation direction along a Z axis, the method comprising:
-
obtaining an alignment compensation module which includes an afocal optical system configured to deviate the angular propagation direction of the light beam when rotated about a Y axis perpendicular to the initial angular propagation (Z axis) direction, the amount of deviation less than the amount of rotation of the afocal optical system; and
rotating the afocal optical system to adjust the path of the light beam through the optical system. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
