Zeiss Laser-Equipped Microscopes Safety Concern

Check if your microscope is affected by this laser safety issue.

The attached notice from Zeiss documents a concern that the shutter may not completely close under conditions that the system indicates that it is “laser-safe,” with the risk that laser light can be reflected into the eyepieces or onto the sample.  Zeiss service technicians will apply corrective service free of charge for affected instruments.

Please contact Bindu Timilsina, Assistant Radiation Officer with UW-Madison EH&S, with any questions or concerns.
