Title
(EN) QUARTERED GEOMETRIC PROPORTION LIGHT SPLITTING DEVICE AND LASER RULING MACHINE WITH THE SAME
(FR) DISPOSITIF DE DIVISION DE LUMIÈRE À PROPORTION GÉOMÉTRIQUE RÉPARTIE PAR QUARTS ET RÉGLEUSE LASER L'INTÉGRANT
(ZH) 四分等比例分光装置及具有该装置的激光刻线机
Abstract
(EN) A quartered geometric proportion light splitting device, includes a first and a second reflective mirrors (41, 11) with 100% reflectivity, a first, a second, and a third light splitting mirrors (21, 22, 31 ) with 50% reflectivity and 50% transmissivity, and a first, a second, a third and a forth focus lenses (12, 23, 32, 42) The first light splitting mirror, the third light splitting mirror and the first reflective mirror paralleled with each other are disposed in sequence in a straight line of an incident collimated light beam After passing through the quartered geometric proportion light splitting device, the collimated light beam is divided into a first, a second, a third and a forth light beams (910, 920, 930, 940) with 25% power of the collimated light beam A laser ruling machine includes the quartered geometric proportion light splitting device
(FR) Un dispositif de division de lumière à proportion géométrique répartie par quarts comprend des premier et second miroirs réfléchissants (41, 11) ayant une réflectivité de 100 %, des premier, deuxième et troisième miroirs de division de lumière (21, 22, 31) ayant une réflectivité de 50 % et une transmissivité de 50 %, ainsi que des première, deuxième, troisième et quatrième lentilles de focalisation (12, 23, 32, 42). Les premier et troisième miroirs de division de lumière et le premier miroir réfléchissant sont parallèles les uns aux autres et ils sont disposés dans cet ordre dans une ligne droite d'un faisceau lumineux collimaté incident. Après avoir traversé le dispositif de division de lumière à proportion géométrique répartie par quarts, le faisceau lumineux collimaté est divisé en premier, deuxième, troisième et quatrième faisceaux lumineux (910, 920, 930, 940) ayant une puissance égale à 25 % du faisceau lumineux collimaté. Une régleuse laser intègre le dispositif de division de lumière à proportion géométrique répartie par quarts.
