What Lens to Use for Photographing Reflective Metal Parts in Vision Inspection




Photographing reflective metal parts is a common difficulty in visual inspection.Due to the high reflectivity and high brightness of the metal surface, once it encounters strong light irradiation, it will produce reflective phenomena, resulting in image quality degradation, thus affecting the accuracy of the detection results.Therefore, when photographing reflective metal parts, you need to choose a suitable lens to solve this problem.


Telecentric industrial lenses are optical lenses that eliminate parallax in traditional industrial lenses.With high resolution, low distortion, large depth of field, constant magnification, imaging stability, etc., it is a more ideal choice in reflective metal parts detection.



Advantages of telecentric lenses for photographing reflective metal parts applications:


1. Eliminate reflections: The telecentric lens adopts a special optical design, which can make the light focus on the same point on the object, thus eliminating reflections.Compared with traditional industrial lenses, telecentric lenses provide more stable image quality and are less susceptible to interference from ambient light.


2. Improve resolution: Telecentric lenses can reduce image distortion and aberration, thus improving resolution.This is very important for the inspection of reflective metal parts, because only a high-resolution image can accurately reflect the details and defects on the surface of the object.


3. Strong adaptability: Telecentric lens has a long working distance and large depth of field, which can obtain clear images at different shooting distances and angles.


Relying on the relevant technology and market experience mastered over the years, POMEAS has launched a variety of types of telecentric lenses and accessories, which can satisfy the needs of the majority of users in high-precision measurement of electronic parts measurement, glass products inspection, metal parts inspection, mechanical parts measurement, injection molding parts inspection and other high-precision measurement needs.
