Title (EN) OPTICAL COUPLING DEVICES
(FR) DISPOSITIF DE COUPLAGE OPTIQUE
Abstract:
(EN) A laser transmitter unit is described, the unit including a laser diode 2 emitting radiation into a lens system. The lens system includes collimating lenses L1, L3 and focussing lenses L2, L4. Additionally, compensating or steering lens S1, S2 are positioned between the collimating lenses L1, L3 and the focussing lenses L2, L4. The steering lenses S1, S2 act to reduce the sensitivity of the focussing lenses L2, L4 to position within the lens system. The position the focussing lenses can be difficult to control particularly when the lenses are welded into position on the laser transmitter unit 1.
(FR) Cette invention concerne une unité émetteur laser, laquelle unité comprend une diode laser (2) chargée d'émettre un rayonnement laser dans un système de lentilles. Ce système de lentilles comprend des lentilles collimatrices (L1, L3) ainsi que des lentilles de concentration (L2, L4). Par ailleurs, des lentilles de compensation ou de direction (S1, S2) sont placées entre les lentilles collimatrices (L1, L3) et les lentilles de concentration (L2, L4). Les lentilles de direction (S1, S2) servent à réduire la sensibilité des lentilles de concentration (L2, L4) à positionner dans le système de lentilles. La position des lentilles de concentration peut être difficile à commander, en particulier lorsque les lentilles sont soudées en position sur l'unité émetteur laser (1).
