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.

Photography Density Measurement Part 2. Geometric conditions for transmission density ICS 37.040.20 G80 National Standards of People's Republic of China GB/T 11500-2008/ISO 5-2.2001 Replacing GB/T 11500-1989 Photographic density measurements - Part 2. Geometric conditions for transmission density (ISO 5-2.2001, IDT) Posted 2008-06-18 2009-02-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis standard is identical with ISO 5-2.2001 "photographic density measurements - Part 2. Geometric conditions" (in English). This standard is equivalent translation ISO 5-2.2001. For ease of use, this standard does the following editorial changes. a) "this International Standard" be replaced by "this standard"; b) use a decimal point instead of a decimal comma ",". ","; c) Delete ISO 5-2. Preface 2001; d) Normative references introductory phrase file to GB/T 1.1-2000 specified key words. This standard replaces GB/T 11500-1989 "photographic transmission density measurement geometry." This standard compared with GB/T 11500-1989, includes the following changes. --- The standard name according to international standard name translated from the original "photographic density measurement geometry" to "photographic density measurements Part 2. Geometric conditions for transmission density "; --- Increasing the foreword and introduction; --- Justifying the introduction of "opal glass" instead of "sphere" for the diffuser and the difference between the transmission ratio and the transmission factor and the like; --- In order to more clearly understand the standard content of the "scope" This section has been clearly defined; at the same time expanding the application Range (Excerpts Chapter 1, 1989 version of Chapter 2, paragraph 2.2); 3.1 The ratio of the flux through the sample and the sample throughput measured from the measuring instrument sampling holes away. T = ΦτΦ j Where. Φτ --- transmission flux; Φ j --- aperture flux. 3.2 The number of transmission factor to take reciprocal base 10 DT = log10 1T = log10 Φ j Φτ 3.3 Lighting or receiving system diffusive measure.
