Scope

Scope: This document specifies the industrial lens interface dimensions suitable for industrial digital cameras using image sensors larger than 31.5mm (Class IV) in the machine vision industry. This document is applicable to guiding industrial camera manufacturers, industrial lens manufacturers, and others in the R&D, design, and manufacturing of large-format industrial cameras and compatible lenses. Main technical content: 1. Terms and definitions: Definitions are provided for professional terms such as "industrial lens", "large-format lens", and "flange distance". 2. Classification of industrial camera imaging surfaces and industrial lens interfaces: Introduces the classification method of industrial cameras based on chip size and the corresponding list of industrial lens interfaces. 3. CFL series large-format industrial lens interfaces: Large-format industrial lens interfaces are divided into three categories: CFL, CFL-II, and CFL-III according to their interface sizes. The document specifies technical indicators such as "thread size", "basic deviation", "tolerance", "flange distance", "distance from the end of the lens to the flange surface", and "distance from the protective glass to the front end of the camera", and provides mechanical drawings of the camera and lens sides for readers' reference.
