The CDRH (Center for Devices and Radiological
Health)- 21CFR1040.10 procedure for measuring laser output is the energy
detectable through a circular aperture stop having a diameter of 7 mm
at a distance of 20 cm from the probe tip or laser diodes.
Konftec's visible red laser diode (typical wavelength
of 660nm laser diode) equipped in the Klas
series is
with the specification of beam divergence 9° (Parallel
Angle) x 19° (Perpendicular Angle).
Because of the divergence of the beam, the distance and the aperture
used, the energy detectable falls within the Class IIIa (wavelength
400nm ~ 710nm visible laser with radiation power <5 mW) laser product
standard.
The typical average power for all 50mW
and some 100mW laser devices shown on the warning logotype in our brochure
and user's guide is <5
mW/cm² as measured in accordance with the procedure described
above. |
