WARNING
10. Photobiological safety
This product is designed and manufactured in accordance with the IEC62471 standard "Photobio-
logical Safety of Lamps and Lamp Systems."
Light emitted from the dia-illumination section of the Ti2-U main body
The photobiological safety of light emitted from the dia-illumination section (aperture of the con-
denser lens) is classified into the risk group shown in the table below.
The distance (hazard distance) from the dia-illumination section when the risk group classification
is the Exempt Group, which does not cause photobiological hazards, is shown below. This table
shows the highest risk when a TI2-D-LHLED LED lamphouse for dia illumination or a D-LH/LC
precentered lamphouse is used as the light source.
Infrared radiation hazard to eyes
Retinal blue-light hazard
The emitted light contains ultraviolet radiation, infrared radiation, and blue light. These light
sources are potentially hazardous and may cause injury if directed at the eyes or skin. Do not
stare at or expose your skin to this light.
Light emitted from the epi-illumination section of the Ti2-U main body
The photobiological safety of light emitted from the epi-illumination section (objective) is classified
into the risk groups shown in the table below.
The distance (hazard distance) from the epi-illumination section when the risk group classification
is the Exempt Group, which does not cause photobiological hazards, is shown below. This table
shows the highest risk when a D-LEDI fluorescence LED illumination system is used as a light
source.
UV hazard
Retinal blue-light hazard
The emitted light contains ultraviolet radiation, infrared radiation, and blue light. These light
sources are potentially hazardous and may cause injury if directed at the eyes or skin. Do not
stare at or expose your skin to this light.
Light emitted from the D-LH/LC precentered lamphouse
The photobiological safety of light directly emitted from the aperture of the D-LH/LC precentered
lamphouse is classified into the risk groups shown in the table below.
The following table shows the distance (hazard distance) from the aperture when the risk group
classification is the Exempt Group, which does not cause photobiological hazards:
UV hazard
Infrared radiation hazard to eyes
Retinal blue-light hazard
The emitted light contains ultraviolet radiation, infrared radiation, and blue light. These light
sources are potentially hazardous and may cause injury if directed at the eyes or skin. Do not
stare at or expose your skin to this light.
When D-LH/LC is not attached to the microscope, remove the lamp cable to prevent the emission
of light.
