Foreword

This standard is identical with ISO 11421.1997 "Optics and optical instruments - Optical transfer function measurement accuracy." This standard is equivalent to translate ISO 11421.1997. For ease of use, this standard also made the following editorial changes. --- "This International Standard" be replaced by "this standard"; --- Delete foreword international standards; --- International Standard Appendix D to this standard "reference." This standard replaces GB/T 13742-1992 "optical transfer function measurement accuracy." This standard and GB/T 13742-1992 main differences are as follows. --- To increase the content of Chapter 3. Terms and definitions, symbols; --- Chapter 4 has increased the impact "coherent light" and "baseline error" for MTF measurement; --- Chapter 4 adds MTF measurement error on a mathematical expression or formula; --- Chapter 7 increased preferences nominal value calculation accuracy table; --- Added Appendix A, Appendix B, Appendix C. Appendix A of this standard is a normative appendix, Appendix B, Appendix C is informative appendix. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee photon science and optics (SAC/TC103) centralized. This standard is drafted by. Shanghai Polytechnic University, East China Normal University. The main drafters of this standard. Huang Weijia, Zhang Hui Yin, Wang Wei students. This standard replaces the standards previously issued as follows. --- GB/T 13742-1992. GB/T 13742-2009/ISO 11421.1997 MTF measurement accuracy

Standard lens measurements shall be strictly in accordance with the specified measurement conditions, the MTF Deviation measured value and the theoretical value of the MTF calculated is not more than 0.05. NOTE. In order to meet the accuracy requirements, the standard lens is usually a simple structure, properties subject to strict regulations. For example, using a 50mm focal length is generally flat Convex standard lens. These lenses and several other standard lens (including afocal system and work in the infrared lens) is not difficult to obtain. 3.1.2 By one or more structurally stable lenses. Check the lens MTF values can not design data (usually a synthetic lens Results) calculated, but by official agencies (conditions permitting preferred national standards laboratory), carried out under the test conditions specified measurement To obtain the amount of its recognized value. 3.2 Symbol Table 1 symbols apply to this standard.
