Device for patterning an optical element

A device for patterning an optical element, comprising:

• a working platform, on which said optical element is carried, moving said optical element toward a first direction and a second direction;
• a linear cutting pedestal mounted above said working platform, and having an upper sliding track at a top of said linear cutting pedestal and a lower sliding track at a bottom thereof;
• a cutting tool positioned in said lower sliding track for moving back and forth in said lower sliding track, said cutting tool being adjusted to an appropriate position according to a predetermined pattern, and a first press force being provided by said cutting tool;
• a weight sliding block, moving back and forth in said upper sliding track, and providing a second press force to said cutting tool;
• and
• a shaft, positioned above said linear cutting pedestal, driving said linear cutting pedestal to move in a third direction, and said third direction being perpendicular to said first direction and said second direction;
• wherein the cutting tool is used to pattern said optical element by means of a linear relative motion between said working platform and said cutting tool, and said predetermined pattern is uniformly formed on the optical element by said first press force of said cutting tool and said second press force of said weight sliding block.
