An apparatus for microsurgical approach in a laser beam on a small spot in the focal plane.

摘要

Approach in Microsurgery Device for a laser beam on a small spot in the focal plane.It consists of a laser source to produce a Laser Beam (1); a Beam Expander (21) laser to expand in straight Section transverse to the laser beam, forming a laser beam; a collimator Lens (23) for parallel Rays divergent Laser Beam Expanded; a l Body to focus the laser beam expanded into a Small Point of the focal plane.This Lens having a Straight Section greater than the straight section of the Expanded Laser Beam; and a means (21) located between the Expander, the collimator (23) and the Focusing Lens, the beam to move laterally expanded.
