Bi-Telecentric Lens: Assisting High-Precision Industrial Inspection!

In the field of industrial visual inspection, bi-telecentric lenses play an indispensable role as a precise visual tool. This article will quickly provide an understanding of the occasions where bi-telecentric lenses are applicable.

A bi-telecentric lens is a special kind of industrial lens designed to address the parallax issues of traditional industrial lenses. It uses a bi-telecentric design, which keeps the image magnification constant within a certain object distance range, effectively avoiding the parallax and unstable magnification problems of traditional industrial lenses.

Versatile Application Scenarios of Bi-Telecentric Lenses

Dimensional Measurement

Bi-telecentric lenses provide high-precision measurement results, suitable for surface dimensional measurement of various products, such as mobile phone component inspection, plastic part inspection, etc. By capturing product images with bi-telecentric lenses and combining them with image processing technology, automated measurement and control of product dimensions can be achieved, improving production efficiency and product quality.

Surface Defect Detection

The high resolution of bi-telecentric lenses makes them suitable for surface defect detection. On the production line, bi-telecentric lenses can capture micro details of the product, such as surface scratches, dents, bulges, etc. Combined with machine vision technology, automated defect detection and classification of products can be achieved, enhancing production efficiency and quality.

Biomedical Research and Other Fields

Bi-telecentric lenses have many unique advantages and can be used for observing and measuring microscopic structures such as cells and tissues.

Advantages of Bi-Telecentric Lenses in Part Measurement

Bi-telecentric lenses are high-precision, high-efficiency industrial lenses capable of accurately measuring complex shapes and high-precision parts. They reveal the smallest shape and surface defects, ensuring the precise manufacturing of parts.

Bi-telecentric lenses can be applied to surface inspection of various types of parts, such as mechanical parts, electronic parts, plastic parts, etc., meeting the needs of different industries and applications, including automotive, electronics, hardware, plastics, communications, and more.

Bi-telecentric lenses have advantages such as consistent magnification and low distortion, and their measurements are non-contact. For plastic part measurement, they can solve the issue of inaccurate measurement data caused by deformation due to movement.

Bi-telecentric lenses have a large depth of field and clear imaging, capable of detecting very small defects and achieving comprehensive inspection. Traditional part measurement methods require a significant amount of time and manpower, while inspection solutions equipped with bi-telecentric lenses can complete a series of high-precision measurements in a very short time and respond quickly, thereby reducing defect rates. This helps improve production efficiency, save production costs, and promote product quality improvement.

In summary, as a high-precision industrial lens, bi-telecentric lenses have a wide range of applications in industrial visual inspection. They provide stable image quality and high-precision measurement results, offering crucial technical support for scenarios like product dimensional measurement and surface defect detection. 

Bi-telecentric lenses have many advantages in measuring part dimensions, such as high precision, high efficiency, non-contact, ease of use, and comprehensiveness. These characteristics make them an ideal tool for modern industrial applications. Using bi-telecentric lenses can enhance production efficiency and quality, lower production costs, and bring more commercial advantages to manufacturers.
