Machine Vision - Lens

1. Overview

Machine vision lenses are optical components designed to capture precise visual data for automated inspection and analysis systems. These lenses interface with industrial cameras to enable high-accuracy imaging in applications ranging from quality control to robotic guidance. Their importance stems from their ability to enhance production efficiency, reduce human error, and enable real-time decision-making in smart manufacturing environments.

2. Major Types and Functional Classification

Type	Functional Characteristics	Application Examples
Fixed Focal Length Lenses	Constant field of view with adjustable working distance	Assembly line defect detection
Zoom Lenses	Variable focal length with manual/remote adjustment	Multi-stage packaging inspection
Telecentric Lenses	Parallel optical path to minimize perspective error	Precision metrology of microcomponents
Wide-Angle Lenses	90 + field of view with distortion correction	Autonomous vehicle navigation systems
Microscopic Lenses	High magnification with working distances <50mm

3. Structure and Components

Typical machine vision lenses consist of: - Optical elements (aspherical glass/ED glass compound) - Mechanical housing with C-CS/FC/M42 interfaces - Adjustable iris diaphragm (f-stop control) - Focus/zoom rings with lock mechanisms - Anti-reflective coating layers - Sensor size matching (1.1"-4/3")

4. Key Technical Specifications

Parameter	Description	Importance
Focal Length	Determines field of view and magnification	Matches imaging area to object size
Aperture Range	Controls light transmission (f/2.8-f/16)	Optimizes depth of field
Resolution	100-500 lp/mm at specific wavelength	Directly affects image clarity
Working Distance	15mm- adjustable range	Accommodates machinery constraints
Interface Type	C /CS /F

5. Application Fields

Primary industries include: - Automotive manufacturing (robotic welding guidance) - Electronics assembly (SMT solder paste inspection) - Pharmaceutical packaging (date code verification) - Food processing (contaminant detection) - Semiconductor production (nanoscale pattern recognition)

6. Leading Manufacturers and Products

Manufacturer	Product Series	Key Features
CCS America	LM Series	6-element multi-coating design
Edmund Optics	59-870 C Series	Telecentric measurement accuracy 0.02%
Cognex	MM series	Integrated lighting control
