LENS OPTICAL FIBRE AND A LASER MODULE

摘要

The inventive optical device and laser module relate to optical devices for optical interfacing of multi-mode and single-mode optical fibres such as /= , /= and others with a radiation source or receiver. The inventive lens optical fibre comprises optical fibre in the form of a light guiding space encompassed by hollow longitudinal channels, and a lens element in the form of a lens space and a neck thermally formed of fibre material on the end thereof. Said channels are closed on the border between the neck and the optical fibre. The laser module comprises a laser emitter and a lens optical fibre which is arranged in the direction of a laser beam. Said lens optical fibre comprises the optical fibre in the form of a light guiding space encompassed by hollow longitudinal channels, and a lens element in the form of a lens space and a neck thermally formed of fibre material on the end thereof. Said channels are closed on the border between the neck and the optical fibre.
