A Telecentric lens is a kind of lens that the chief rays are parallel to the optical axis. There are three kinds of telecentric lens, that is the object-space telecentric lens, image-space telecentric lens, and the bi-telecentric lens. Telecentric lens is always the core business of� Canrill Lens. After continuous research and development for 11 years, Canrill has successfully developed 1700+ kinds of lenses, and the number is still increasing, to meet the diverse and growing applications at the best telecentric lens price.
Difference Between Object Space Telecentric Lens And Bi Telecentric Lens
Telecentric lenses have two types of telecentricity: telecentric objective space and image space telecentricity (referring to the entrance and exit pupil positions, respectively). Therefore, telecentric lenses are divided into: object space telecentric lens, image space telecentric lens, and bi telecentric lens.
Object Space Telecentric Lens
In general, a machine vision telecentric lens refers to an object space telecentric lens. If the entrance pupil of the lens is located at an infinite position in the image side (all objects behind the objective lens), it can be called an object space telecentric lens.� The chief ray originated from optical axis is parallel with optical axis in object side ( or to say have very small angle �¸ which is called telecentricity in telecentric lens specs), while in image side is not parallel.

In the optical design, object space telecentricity is achieved by placing the system's iris diaphragm at the intersection of the front-end groups. Since the entrance pupil is at infinity, the field of view is constant and has no field angle. Since the chief ray (which defines the system's field of view) passes through the optical axis at the aperture stop, when the pupil is at infinity, the ray is parallel to the optical axis and the field of view is zero. By contrast, any entrance pupil within a finite distance of the lens results in a non-parallel fiber.
Telecentric illuminator is of great significance to the image processing system. Providing stable and reproducible illumination conditions, the telecentric illuminator produced by Canrill can help the image processing tools, such as our� machine vision telecentric lens, to better capture the visual image of the object. Better clarity and WBC, higher telecentricity Especially suitable for round workpiece measurement Machine Vision Illuminator Specification Telecentric Illumination Regarding the illumination techniques in machine vision, the concept of telecentric light rays collimating and parallel to the optical axis also applies. Canrill telecentric illuminator machine uses optical devices to direct light from fiber-optic guides or LEDs to the object being examined, producing high-contrast silhouettes. TV central luminescence improves edge contrast and measurement accuracy by reducing diffuse reflection from objects. The collimating light leaves the illuminator and remains on the collimating surface as it strikes the object. In contrast, light from a standard backlight expands and interferes with each other, resulting in diffuse reflection.

1 Accurate depth information: The TOF camera can provide up to 300,000 depth information points, which is more accurate and rich than traditional binocular vision, helping to build high-precision 3D models. This is very important in scenarios such as autonomous driving and robot navigation. 2Anti-environmental interference :TOF cameras can maintain good depth perception performance in complex environments, such as direct sunlight and haze, overcoming the limitations of traditional vision systems. 3 Cost advantage: As the cost of TOF chips and components declines, the overall cost of TOF cameras is also decreasing, which is conducive to large-scale commercial applications. 4 Wide application prospects: In addition to the fields of autonomous driving, robotics, and medical care you mentioned,TOF technology can also be applied to 3D modeling, AR/VR, human-computer interaction, security monitoring and other fields, with broad prospects.
