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.
