CDRH Laser Devices Class IIIa Power Test
Complied FDA Performance Standards for Laser Products

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 20cm from the probe tip or laser diodes.

Konftec's visible red laser diode (typical wavelength of 660nm laser diode) equipped in Aculas-HB-850A and 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 the 50mW laser device shown on the warning logotype in our brochures and user's guide is <5 mW/cm² as measured in accordance with the procedure described above.
