WARNING

7. Photobiological safety
This product is designed and manufactured in accordance with the safety standard IEC 62471
"Photobiological safety of lamps and lamp systems."
Illumination near the stage and light from the binocular part of the eyepiece tube or the teaching
head, and light from the camera port of the trinocular eyepiece tube are classified into the following
risk group. The distance (hazard distance) from the vicinity of the stage or from the binocular part of
the eyepiece tube or the teaching head, or from the opening of the camera port where the risk group
classification is equivalent to the exempt group that does not cause photobiological injury is as
follows.
Retinal blue light hazard
Infrared radiation hazard to eyes
Illumination in risk group 3 can be hazardous. Pay attention to brightness adjustment by the
brightness control knob and avoid looking strong light for a long time.
• The LED light source is built in at the bottom part of the microscope. Illumination light from the
field lens goes through the condenser and illuminates the specimen. Do not stare at the
condenser lens, specimen or periphery of the specimen, and do not look into the field lens.
• Do not look into strong light from the binocular part of the eyepiece tube or the teaching head.
• Do not remove the eyepieces from the binocular part when illumination is turned on.
• Do not look into strong light from the camera port from directly above.
• When you do not attach the camera, attach the supplied cap to the camera port.
8. Do not look into the illumination section.
The following warning label indicating the highest risk (Risk Group 3) to photobiological safety is
affixed on the handle side of the stage to remind the user of the following precautions. (For the
locations of this label, see the figure in "Chapter 1 Nomenclature of Each Part.")
WARNING (Risk Group 3)
IR and possibly hazardous light is emitted from the camera port when the trinocular eyepiece
tube is used.
Never look into the camera port.
CAUTION (Risk Group 2)
Possibly hazardous light is emitted from the condenser lens when diascopic illumination is
used.
Do not stare at emitted light. It may be harmful to the eyes.
NOTICE (Risk Group 1)
Possibly hazardous light is emitted from the eyepiece lenses when diascopic illumination is
used.
Avoid long-time microscopic observation with strong illumination.
