Invention novelty:This invention is a system that could permanently mark the microscope slide with an optical laser.

Technical details
Johns Hopkins researchers have been working on developing equipment that could mark microscope slides with laser. The design of the system is proposed allowing for laser marking of microscope slides while maintaining the eye-safety for the operator. Spot size could be changed by varying pulse energies. Laser-marking is visible through the entire depth of microscope slide. High resolution marking is achieved. Marking has been automated with step sizes of 1 µm or less and recognizable shapes.
