Safety Information

-4-

ISO15004

This report provides information about the hazard to the examinee’s eyes in compliance with

ISO15004 (1997).

1. The spectral characteristics of radiant flux exiting from this instrument are as follows:

2. Photochemical radiance

The photochemical radiances at each photography modes irradiated from this instrument to

the examinee’s eyes are indicated below. All the values in the following table were measured

when the instrument was operating at maximum light intensity and maximum aperture.

3. The above values are spectrally weighted radiance on the pupil of examinee’s eyes in each

wavelength.

La gives the measure for eyes in which the crystalline lens has been removed (aphakes) or for

eyes of infants. Lb gives this measure for eyes in which the crystalline lens is in place except

for infants’.

Spectrally weighted photochemical radiances La and Lb give a measure of the potential that

exists for a beam of light to cause photochemical hazard to the retina.
