Abstract
Abstract A laser optical apparatus for operation under a microscope comprises: a laser beam introducing 45° reflector arranged between two optical axes so as not to impair the range of vision frontwardly of a binocular telescope for operation, a parabolic mirror with a surface displaced from an axis for condensing introduced beams of laser and serving as an objective lens of the microscope, a plane reflector driven by motors to direct the condensed beams of laser and an optical axis of the microscope, and a maneuvering mechanism including a stick for operating said motor.

A laser optical apparatus for operation under a microscope comprising: a laser beam introducing 45° reflector arranged between two optical axes so as not to impair the range of vision frontwardly of a binocular telescope for operation, a parabolic mirror with a surface displaced from an axis for condensing introduced beams of laser and serving as an objective lens of the microscope, a plane reflector for directing the condensed beams of laser and an optical axis of the microscope, and a servo mechanism for controlling the position of said plane reflector.
Claim 3
Dependent Claim
30 words
A laser optical apparatus as claimed in claim 1 wherein said servo mechanism includes a stick mechanism for instructing said servo mechanism to controlling the position of said plane reflector.
Claim 4
Dependent Claim
24 words
A laser optical apparatus as claimed in claim 1 wherein said servo mechanism includes bridge circuits for controlling the position of said plane reflector.
Claim 5
Dependent Claim
66 words
A laser optical apparatus as claimed in claim 1 wherein said servo mechanism includes an L-shaped bed for rotationally supporting said plane reflector, a first motor mounted on the vertical member of said L-shaped bed for rotating said plane reflector about a horizontal axis and a second motor rotationaly supporting the horizontal member of said L-shaped bed for rotating said L-shaped bed about a vertical axis.
