Basic standard as the laser product safety test, GB7247.1-2001 " the safety first part of laser product: device class, requirement and users' guidebook " is after replacing GB7247-1995, very large variation has occurred in Laser Radiation Measurement, and for example: GB7247-1995 has stipulated 10
-5and 5 х 10
-4the reception solid angle of sr, GB7247.1-2001 has stipulated the acceptance angle of 0.1rad; The time reference that GB7247-1995 is greater than the laser emission employing of 400nm for wavelength is 1000s, and the time reference that GB7247.1-2001 adopts is 100s.Because these change, cause measuring the laser emission energy received very large variation has occurred, reached at the emitter limit value of employing is followed originally also fully different, thereby has caused the difference of laser classification judgement.
At present domestic and international relevant laser emission testing tool, have some general drawbacks in judgement laser emission classification: the focal length of lens, optic probe length, the aperture of the diaphragm etc. do not meet the demands, do not consider to reach the test request of the emission limit, can't realize the judgement to the laser emission grade; And the regulative modes such as the supporting and location of support, rotation are inconvenience extremely.
