A semi transparent imaging film is placed in front of the imaging illuminometer, and the light source is irradiated onto the white semi transparent film. The illuminance distribution of the light source is formed behind the semi transparent film. The imaging illuminometer captures the illuminance distribution, and the illuminance distribution of the illuminated surface is calculated and processed. Used for measuring the illuminance distribution of special light sources for lens imaging, small LED light sources, and analyzing the quality of low-power laser spot imaging.
Also customized IR, max 1000nm for Irradiance distribution test , for example , use in IR LED, VCSEL LASER.
