Abstract
The invention relates to an optical device comprising an emitting source and a partly-reflective element which is adapted for receiving an emitted light beam. This element is tilted in a small angle with respect to the emitted light beam. A portion of the emitted light beam is reflected by the partly-reflective element towards a transmittive element which is arranged in close proximity to the emitting source and adapted to receive and transmit the reflect portion. The transmittive element is arranged for at least partly fixing or positioning an optical fiber, which is emitting the input light beam, and provided for transmitting the laterally offset reflected portion of the input light beam away from the input fiber.
Claims11
An optical device, comprising:
- an emitting source adapted to emit a light beam,
- a partly-reflective element adapted for receiving the emitted light beam, wherein the optical axis of the partly-reflective element is tilted in a small angle with respect to the emitted light beam, and the reflective element reflects a portion of the emitted light beam, and
- a transmittive element is arranged in close proximity to the emitting source and adapted to receive and transmit the reflected portion,
- wherein the transmittive element is arranged for at least partly fixing or positioning an optical fiber, which is emitting the input light beam, and provided for transmitting the laterally offset reflected portion of the input light beam away from the input fiber.
