LASER OPTICS WITH LATERAL AND ANGULAR SHIFT COMPENSATION

摘要

A telecentric F-theta lens is added to the optical chain of a laser used to cut stent patterns into a stent tube to facilitate positioning and alignment of the laser beam and to compensate for lateral and angular shift of the beam spot.

主权项

1. A laser system for cutting a stent pattern into a stent tube, comprising:
a laser for generating a laser beam; a mirror for reflecting the laser beam at a desired angle; and a telecentric F-theta lens configured to receive the reflected laser beam and to focus the reflected laser beam onto a stent tube.
