In the fast-paced world of machine vision, capturing high-quality images is essential. Opto Engineering, a leader in advanced optical components, offers a variety of lenses tailored to meet the needs of different applications. This article will explore two specific lens types offered by Opto Engineering—telecentric and 360° lenses. We’ll look at their characteristics, benefits, and how they improve image quality in machine vision.

Introduction to Opto Engineering

Opto Engineering is well-known for its expertise in optical engineering and its dedication to providing high-quality optical solutions. They offer a wide range of products, including lenses, lighting systems, and cameras, all designed to improve image quality and performance in machine vision applications. Opto Engineering’s innovative designs and precision make them a trusted name in many industries, from automation to scientific research.

Telecentric Lenses

What Are Telecentric Lenses?

Telecentric lenses are specialized lenses that eliminate perspective distortion. Unlike regular lenses, which change magnification as the object distance changes, telecentric lenses keep the magnification constant no matter how far the object is from the lens. This unique feature makes them perfect for applications needing precise measurements and high-resolution imaging.

Purpose and Applications

Telecentric lenses ensure accurate and consistent image capture, making them crucial for:

• Metrology: Measuring object dimensions with high precision.
• Inspection: Checking for defects in manufacturing processes.
• Machine Vision: Enhancing the accuracy of robotic guidance systems.

Opto Engineering’s Telecentric Lenses

Opto Engineering offers a wide range of telecentric lenses to meet various application needs, including:

• TC CORE Series: These compact telecentric lenses are designed for integration into automated systems, offering the same precision in a smaller size. They are suitable for measurement systems, such as dimensional and geometric control, and high-precision gauging. The TC CORE series is known for its lightweight and compact design, making it easy to install and handle.
• TC4K Series: These lenses are designed specifically for line scan cameras, providing high resolution and low distortion. They are perfect for applications requiring detailed inspection and quality control on production lines. The TC4K series is optimized for telecentricity and resolution, ensuring sharp and accurate images.
• LT Series: These large-format telecentric lenses are used for applications involving large sensors, such as flat panel display inspection and solar panel examination. The LT series provides excellent image quality over a wide field of view, making it ideal for inspecting large objects with high precision.
• TCDP Series: These lenses are used for 3D measurement and automated inspection. They feature integrated telecentric illumination, providing consistent and uniform lighting for high-accuracy measurements. The TCDP series is suitable for applications such as 3D scanning and surface inspection.

360° Lenses

What Are 360° Lenses?

360° lenses, also known as omnidirectional lenses, capture a complete panoramic image of their surroundings. These lenses provide a full view around the lens, making them ideal for applications needing a comprehensive field of view.

Purpose and Applications

360° lenses are mainly used in:

• Surveillance: Providing comprehensive coverage in security systems.
• Robotics: Helping robots navigate and interact with their environment effectively.
• Inspection: Allowing the examination of objects from multiple angles in a single image capture.

Opto Engineering’s 360° Lenses

Opto Engineering offers innovative 360° lenses that ensure high image quality and functionality, including:

• PC Series: These lenses offer high-resolution panoramic views and are suitable for various industrial applications. They provide a clear and detailed 360° view, making them ideal for surveillance and inspection tasks.
• PCCD Series: Compact 360° lenses designed for space-constrained environments, providing the same comprehensive field of view in a smaller package. These lenses are perfect for applications where space is limited but a wide field of view is still required.
• PCMP Series: These catadioptric lenses are designed for 3D measurement applications, capturing the entire 360° view of an object. They are ideal for automated quality control systems, allowing for precise and comprehensive inspection.
• PCBP Series: These lenses are specifically designed for bottle and cylindrical object inspection, providing a complete view of the object in a single shot. They ensure high-speed and accurate inspection, making them ideal for quality control in packaging and manufacturing industries.

Comparison of Telecentric and 360° Lenses

Key Differences

• Field of View: Telecentric lenses provide a narrow, precise field of view, perfect for measurement and inspection. In contrast, 360° lenses offer a wide, panoramic field of view for comprehensive coverage.
• Distortion: Telecentric lenses minimize perspective distortion, making them ideal for applications requiring exact measurements. 360° lenses, on the other hand, introduce some distortion due to their wide field of view.
• Applications: Telecentric lenses are used in high-precision and consistency applications, such as metrology and machine vision. 360° lenses are better suited for surveillance, robotics, and applications requiring a complete view of the surroundings.

Choosing the Right Lens

To select the right lens for your application, consider the following factors:

• Application Requirements: Determine if you need high precision (telecentric lenses) or a wide field of view (360° lenses).
• Space Constraints: Consider the available space for lens integration. Opto Engineering offers compact versions of both lens types.

• Image Quality: Evaluate the level of image quality required. High-resolution options are available for both lens types to meet demanding imaging needs.
• Lighting Conditions: Assess the lighting environment of your application. Some lenses may perform better under specific lighting conditions.

Summary

Opto Engineering provides advanced optical solutions to enhance image quality in machine vision applications. Their telecentric lenses offer unparalleled precision for tasks requiring exact measurements, while their 360° lenses provide comprehensive panoramic views for applications needing a wide field of view. Understanding the specific characteristics and applications of these lenses is crucial for selecting the right optical solution for your needs. By leveraging the expertise and innovative products of Opto Engineering, you can ensure optimal performance and accuracy in your machine vision applications.
