Patent ID: 8422128

Claim:
A modular objective assembly for use with a microscope having an eyepiece comprising: a mounting modular body mountable onto a turret of the microscope including an objective having an optical axis that permits an image beam to be emitted through the objective toward the eyepiece of the microscope and an objective mirror positioned at an angle to the optical axis of the objective; a modular laser assembly positioned on a first side of the objective mirror for directing laser energy toward said objective mirror so that the laser energy is reflected off the objective mirror and through the objective in a direction that is substantially aligned with the optical axis, the modular laser assembly being adapted to be received in said mounting modular body; and a modular indicator assembly including a source of light, a collimating lens, and an indicator mirror, received in the modular body and positioned on the opposite side of the objective mirror, the indicator mirror directing a beam of light emitted from the indicator light source through the collimating lens toward the opposite side of the objective mirror to reflect the indicator light in a direction opposite to the direction of the laser energy to permit an optical representation at the eyepiece of the microscope of the position of the laser energy being emitted through the objective.
