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

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.

Lenses
Lenses have many applications ranging from the simple collection of a laser beam to precision imaging and image transfer. Lenses are classified as single lenses, cylindrical lenses and achromatic lenses. These lenses are made of BK7, fused silica and CaF2. Special focusing systems can be designed by our engineers upon request.

Positive focus length. Most suitable where one conjugate is more than five times the other, e.g. in sensor applications or for use with near collimated light. Also where both conjugates are on the same side of the lens, e.g. as an add-on lens to increase the numerical aperture.
Most suitable where the conjugates are on opposite sides of the lenses and the ratio of the distances is less than 5:1, e.g. as simple image relay components.
Negative lens with the form most suitable where one conjugate is more than five times the other, e.g. producing divergent light from a collimated input beam.
