Collimation Assembly for an Imaging Device

摘要

A collimation assembly includes a body, at least four light sources, and at least four collimation lenses. The body has inner surfaces that define at least four hollow portions extending through the body between opposed first and second sides thereof, each hollow portion having opposed first and second openings at the first and second sides of the body, respectively. Each light source is disposed at the first opening of one of the at least four hollow portions and controllable to emit a light beam therethrough. Each collimation lens is disposed at the second opening of one of the at least four hollow portions to receive the light beam emitted by the light source disposed at the first opening and diverge the light beam as the light beam passes through the collimation lens. The at least four light sources and the at least four collimation lenses are supported by the body.

主权项

1. A collimation assembly, comprising:
a body having inner surfaces that define a plurality of hollow portions extending through the body; a plurality of light sources on first sides of the plurality of hollow portions; and a plurality of collimation lenses on second sides of the plurality of hollow portions opposite the first sides, each of the collimation lenses for receiving a beam of light from a respective one of the plurality of light sources at a light incident surface and passing the beam of light through a light exit surface,
wherein each of the light incident surfaces of the plurality of the collimation lenses defines a focal point a focal length away from said each of the light incident surfaces and each of the plurality of light sources is a distance away from a respective one of the plurality of collimation lenses that is less than the focal length.
