Abstract
Microsurgical laser device for guiding a laser beam to a desired target. The device includes a laser head supported in a relatively horizontal orientation by a counterbalanced articulated support arm which provides for elevational positioning of the laser head as well as rotation of the laser head about two parallel spaced apart vertical axes. The support arm, in turn, is rotatably supported by a vertical post defining a third vertical axis. Threadably connected to one end of the laser head is an articulated laser guide arm having a precision telescopic first section followed by four rotatable mirror sections each of which is adapted to redirect a beam 90.degree. along a plane perpendicular to the axis of the incident path. Each section is precision made to obviate the need to adjust the mirror or align the arm. The support arm permits easy approximate positioning of the laser head in the vicinity of the laser beam target while the relatively short pre-aligned articulated laser beam guide provides for quick precise aiming of the laser beam. The vertical post is supported by a base cabinet that contains the power supplies. The controls of the laser beam characteristics such a power …
