The role of industrial Macro Lens

Macro Lens has many applications in industry, such as ‌ for plastic parts inspection, ‌ for spring appearance inspection and bar code recognition. ‌ To be specific, applications for ‌Macro Lens include: ‌

Plastic parts inspection: ‌ capture plastic parts images by Macro Lens, ‌ and magnify them several times, ‌ can be more clearly and quickly detect plastic parts defect points, ‌ remove defective products, ‌ to ensure product quality. 
‌
Spring appearance detection: ‌ The use of double macro industrial lens, ‌ into 90° Angle design, ‌ from two directions at the same time to capture images, ‌ better obtain high quality images, ‌ high precision to complete the detection. ‌

Bar code recognition: ‌ macro lens can clearly and efficiently identify the product bar code, ‌ to provide valuable information for production, ‌ in order to take corresponding measures in the production process. ‌
Macro Lens is widely used in machine vision automation. Its main purpose is to check the appearance and quality of high-speed moving products on the manufacturing line and to detect subtle defects that are difficult for the naked eye. ‌ The use of these lenses greatly improves the efficiency and effect of industrial manufacturing, ‌ is an indispensable part of the machine vision system

In the machine vision system, the role of the lens is to image the target on the light sensitivity of the image sensor, which has a great impact on the quality of product detection imaging, and is an indispensable part of the machine vision detection system. The industrial lens plays the role of the eye in the machine vision system, and feedbacks the product detection to the industrial camera. Industrial lens is a kind of high-performance resolution lens, using ultra-low distortion design technology, reduce the distortion rate, can more truly reflect the image effect. Because the distortion technology can effectively reduce the reflection loss of the lens, reduce glare, increase contrast, effectively improve the color reproduction degree, improve the clarity of the image.

The combination of industrial lenses and industrial cameras greatly improves the efficiency and effect of industrial manufacturing

The quality of the lens also directly affects the overall performance of the machine vision system, so in the machine vision system, industrial lenses also play a key role.

Cnomax Vision Industrial lenses generally refer to the application in the industrial field, industrial lenses are divided into long focus, short focus and zoom lenses according to the detection requirements and different measurement objects; According to the magnification of the lens, it can be divided into fixed magnification lens, manual magnification, manual fine tuning, fixed-frame fixed magnification lens, electric magnification lens, according to the different resolution can be divided into 5 million pixels, 2 million pixels lens. It is a telecentric lens that meets the high requirements of lens distortion in machine vision, and adopts a unique parallel optical path design technology, which has the characteristics of high resolution, large depth of field and low distortion, and is very suitable for application in machine vision equipment.

Used in machine vision detection can be used to locate highly reflective objects, such as metal, glass, film, chip and other surface scratch detection, chip and silicon chip damage detection, MARK point positioning, Glass cutting machine, dispensing machine, SMT testing, paste machine and other industrial precision alignment, positioning, parts confirmation, size measurement, industrial microscopy and other CCD vision alignment, measuring devices and other fields, has a great market development space.

Another characteristic of industrial lenses is their spectral characteristics, which are mainly affected by the interference characteristics of the lens coating and the absorption characteristics of the material. It is required that the light with higher resolution of the lens should be matched with the illumination wavelength and the wavelength accepted by the CCD device, and the light transmittance of the optical lens to the wavelength should be increased as much as possible. Some special effects can be achieved by selecting the appropriate filter in the imaging system. In addition, the design of imaging optical path also needs to pay attention to the influence of various stray light.

The lens is also an essential part of TV monitoring, the lens and the CCD industrial camera can be used to image the distant target on the CCD target surface of the industrial camera, and then through it the optical image formed by the optical imaging system into a video or digital signal.

Cnomax Vision Industrial lens in the use of ultra-low distortion design, low distortion rate, with a variety of optical correction methods, to minimize the occurrence of pixel difference, so that it can also maintain a high MTF value in the frequency band with high spatial frequency number, high contrast clarity, strong mechanical design of the lens, adjusted locking device, It is very suitable for factory automation, machine vision, image processing and other occasions with very high picture quality requirements, can be used with more than one million pixels 1/3, 1/2, 2/3 industrial cameras, widely used in industrial safety monitoring, high precision measurement, detection, identification and other industrial machine vision and image processing systems.
