HIGH RESOLUTION LASER LABELING OF MICROSCOPIC GLASS SLIDES AND HISTOLOGICAL SECTIONS

摘要

The present invention is directed to a device and a laser, eye-safe method for laser marking slides for use in conjunction with a light microscope. The device is an attachment for a light microscope that allows the operator to make marks on preparations of biological tissues or other materials placed on a glass slide or between a glass slide and a cover slip. The marks can be used to indicate or highlight a microscopic structure or feature of interest. The marking on the slide is performed as the specimen is examined, without having to remove it from the microscope stage. In this way the invention has application in a biomedical or pathology laboratory for diagnostic, research, archival, and teaching or training purposes.

主权项

1. An eye safe system for in-situ permanent marking of microscope slides comprising:
a light microscope for observing the slide, having a light source, a sample stage, and condenser, objective, and occular lenses; a laser source configured to generate a laser beam for marking the slides; a prism for directing the laser beam; a condenser through which the laser light travels; and a mechanism for rendering the marking system eye-safe to the operator.
