QUARTERED GEOMETRIC PROPORTION LIGHT SPLITTING DEVICE AND LASER RULING MACHINE WITH THE SAME

摘要

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
