Abstract
An optical device includes two or more light sources configured for providing input light beams having different wavelengths. The optical device also has a curved reflective element configured to receive the input light beams to provide two or more reflected light beams. The optical device also has a cylindrical lens for each of the reflected light beams configured to transmit each of the reflected light beams to provide a corresponding collimated output light beam.
Claims20
An optical device comprising:
- a first light source for emitting a first input light beam;
- a second light source for emitting a second input light beam;
- a third light source for emitting a third input light beam;
- a curved reflective element configured to:
- receive the first input light beam and provide a first reflected light beam;
- receive the second input light beam and provide a second reflected light beam;
- and
- receive the third input light beam and provide a third reflected light beam;
- a first cylindrical lens disposed in a first light path of the first reflected light beam and configured to receive the first reflected light beam and provide a first collimated output light beam;
- a second cylindrical lens disposed in a second light path of the second reflected light beam and configured to receive the second reflected light beam and provide a second collimated output light beam;
- a third cylindrical lens disposed in a third light path of the third reflected light beam and configured to receive the third reflected light beam and provide a third collimated output light beam;
- and
- a planar waveguide positioned to receive the first collimated output light beam, the second collimated output light beam, and the third collimated output light beam.
