Scope
GB/T 10987-2009 is the English-translated version of 光学系统 参数的测定.
GB/T 10987-2009 is the Chinese national standard on optical systems - determination of parameters, in the field of image technology. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 September 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2009. Classification: ICS 37.020, CCS N35. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

Foreword
This standard replaces GB/T 10987-1989 "Determination of the optical system parameters." This standard and GB/T 10987-1989 main differences are as follows:
--- Remove the GB/T 10987-1989 Chapter 2, "in the title the term" word;
--- The GB/T 10987-1989 Chapter 3, Section 4, Chapter 5 and Chapter 6 into the same chapter entitled to "measured parameter";
--- Remove the GB/T 10987-1989 Chapter 7. 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. Participated in the drafting of this standard. Nanjing Jiangnan Yong new Optical Co., Ltd., Ningbo Yongxin Optics Co., Ltd., Suzhou has an optical instrument Limited. The main drafters of this standard. Pingqiong Hui, Zhang Hui Yin. This standard replaces the standards previously issued as follows:
--- GB/T 10987-1989. Determination of the optical system parameters

This standard specifies the measurement side of the optical system focal length, field of view, magnification and aperture (relative aperture and the numerical aperture) four optical parameters Law, the basic requirements of measuring apparatus and measurement. This standard applies to the measurement microscope visible spectrum applications, binoculars and camera, projection, plate lens and other optical parameters.
