What this standard covers

This standard specifies the diffuse transmission density measurements and f/4. 5, f/1. 6 transmission density of the projection geometry. Diffuse transmission density is mainly used in transparent illuminator (check sheet box) to watch the video, contact with the printed image and diffuse illumination system with the projected image measurement. Mainly used to measure the density of the image projection with a condenser. Although the density measurement methods specified in this standard is mainly used for image measurement, but also often applied to the measurement filters and other transparent materials.
