¿Qué es una lente de visión artificial??
Una lente de visión artificial es un componente crítico en un sistema de visión artificial., que se utiliza a menudo en la fabricación, robótica, y aplicaciones de inspección industrial. La lente ayuda a capturar imágenes., translating light waves into a digital format that the system can understand and process. The quality and characteristics of the lens can greatly affect the system’s ability to accurately identify, measure, or inspect objects.
What are the types of machine vision lenses?
Some common types of machine vision lenses include:
1.Fixed focal length lenses: These lenses have a fixed focal length and provide a constant magnification for capturing images of objects at a specific distance from the lens. They are suitable for applications where the working distance and object size remain constant.
2.Lentes de zoom: Zoom lenses offer adjustable focal lengths, allowing users to change the field of view and magnification as required. They provide flexibility in capturing images of objects at varying distances.
3.Telecentric lenses: Telecentric lenses are designed to produce parallel rays of light, which means that the chief rays are perpendicular to the image sensor. This characteristic results in an accurate and consistent measurement of object dimensions, making them suitable for precision measurement applications.
4.Wide-angle lenses: Wide-angle lenses have a short focal length and a wide field of view, making them useful for applications that require capturing images of large areas or scenes.
When selecting a machine vision lens, factors to consider include the desired working distance, campo de visión, resolution, image quality, lens mount compatibility, and the specific requirements of the application.
What are the features of machine vision lenses?
The features of machine vision lenses can vary depending on the specific lens manufacturer and model. Sin embargo, some common features of machine vision lenses include:
1.High-resolution optics: Machine vision lenses are designed to provide clear and sharp images, often matching the resolution capabilities of high-resolution cameras.
2.Low distortion: Lenses with low distortion ensure that the image captured is accurate and undistorted, especially for applications that require precise measurements or inspections.
3.Broad spectral range: Some machine vision lenses are designed to work with different wavelengths of light, allowing for applications that utilize visible light, ultraviolet (ultravioleta) luz, infrared (IR) luz, or multispectral imaging.
4.Variability and flexibility: Certain lenses, such as zoom lenses, offer adjustable focal length and field of view, providing the ability to capture images at varying magnifications and object distances.
5.Telecentricity: Telecentric lenses produce parallel rays of light, resulting in a consistent magnification and accurate measurement of object dimensions, regardless of the object distance.
6.Focus adjustment: Machine vision lenses often provide manual or motorized focus adjustment, allowing users to optimize the image sharpness for different object distances.
7.Compact and lightweight design: Machine vision lenses are typically designed to be compact and lightweight, making them suitable for integration into vision systems and minimizing the overall footprint.
8.Mount compatibility: Machine vision lenses are available with various lens mounts (such as C-mount, F-mount, M42, etc.), ensuring compatibility with a wide range of cameras or interfaces.
9.Environmental durability: Some machine vision lenses are designed to withstand harsh industrial environments, with features like robust housing, dust-proofing, and resistance to vibrations or temperature variations.
10.Cost-effectiveness: Machine vision lenses often aim to provide cost-effective solutions for imaging applications, striking a balance between performance and affordability.
It’s important to evaluate the specific requirements of your machine vision application and choose the lens features that best suit your needs.
