Description
technical field [0001] The invention relates to a pulsed xenon lamp, in particular to a pulsed xenon lamp with driving power for a lens transmittance tester. Background technique [0002] The lens transmittance tester can be used to test the transmittance of lenses of various materials to different wavelengths of light, so as to perform broad-spectrum non-destructive and rapid measurement of the transmittance indicators of various finished lenses. This measurement method has high precision , At the same time, it is reliable and convenient to operate, so the lens transmittance tester has been widely used in the field of glasses manufacturing and optical processing. [0003] At present, the lens transmittance measuring instrument usually uses a pulsed xenon lamp with a driving power supply, including a pulsed xenon lamp and a driving power supply. The pulsed xenon lamp with a GG17 glass lamp sealing structure made in Japan is used. The structure of the pulsed xenon lamp is as ...
