Advantages of telecentric lenses in machine vision system inspection

Industrial lenses are one of the key components of machine vision systems . Compared with ordinary industrial lenses, high-quality telecentric lenses can perform various forms of optical measurements. Therefore, telecentric lenses are mainly used for dimensional measurement and defect detection of high-precision products, and their technical advantages in high-precision inspection applications have gradually been revealed.

Telecentric lenses are specially designed for industrial inspection and automated machine vision applications, and can provide users with solutions. The product features are as follows:

1. Small telecentricity, high resolution, small distortion, less than 0.1% distortion

2. Able to achieve uniform lighting without image vignetting effect;

3. Within the depth of field range, there is no change in magnification and the target image size remains unchanged.

4. Bi-telecentric design on object side and image side, high light transmittance

5. Increased depth of field, telecentric lenses have a greater depth of field than ordinary lenses

6. Industrial fixed magnification and working distance

7. Lightweight outer diameter, suitable for installation in small spaces

8. Excellent optical performance and quality, high cost performance

9. Any combination of coaxial light illumination, can be used with 1/6”, 1/3”, 1/2” industrial cameras

10. Specially designed for measurement and measurement, suitable for factory automation machine vision applications

Telecentric lenses are mainly used in visual positioning of mechanical equipment, semiconductor inspection, chip and wafer inspection, dispensing positioning, LCD inspection, printing machinery, parts OCR identification, machine vision laboratory and image processing, positioning industry and other fields.
