摘要 |
The present invention relates to a device for processing a light guide plate and comprises a laser generation unit generating a laser beam; a diffractive optical element (DOE) lens holder unit comprising a DOE lens which passes and splits the laser beam; and a focus lens holder unit comprising a focus lens positioned in the lower part of the DOE lens holder unit. The DOE lens holder unit comprises a plurality of DOE lenses that the number of splitting beam is different. The DOE lenses are moved to a transparent position that the laser beam selectively passes. |
