How To Select A Telecentric Lens? What Factors Should Be Considered?
As we all know, telecentric lens is a special industrial lens type designed for machine vision applications. There is no fixed rule for its selection, and it mainly depends on whether it can meet the needs of shooting.
How to select a telecentric lens? What factors should be considered?
In general, before choosing a telecentric lens, the following factors need to be considered:
Focal length and field of view
It is necessary to choose the appropriate focal length and field Angle according to the actual use requirements and the size and characteristics of the target. Longer focal lengths can provide higher resolution and detail, while larger field angles can cover a wider area.
The focal length of a telecentric lens is usually between 17mm and 135mm, and the choice of focal length mainly depends on what you intend to shoot. Landscape photographers may need a wider focal length, while architectural photographers may need more than 35mm.
The choice of focal length for different shots
Optical quality
Choose a telecentric lens with a high-quality optical design and manufacturing process to ensure the clarity and accuracy of the viewing image. Optical quality includes lens material, coating technology, refractive index of lens components and so on.
Aperture size
Aperture size affects the performance of the lens in low light environments and the control of background depth. In general, an aperture of f/2.8 or larger is more suitable for use in dark environments, while an aperture of f/4 or smaller is more suitable for use in bright environments.

Design and structure
Consider the design and structural features of the telecentric lens, such as focal segment adjustment system, focusing adjustment system, lens coating and other functions. The design and structure of these aspects will directly affect the ease of use and observation effect of telecentric lens.
Budget and actual needs
When choosing a telecentric lens, you also need to weigh various factors according to your personal budget and actual observation needs. Some telecentric lenses may be more expensive, but can provide better viewing results; There are some economy products in terms of performance and price may also be a good choice. It is generally recommended to choose cost-effective products under the premise of meeting demand.
Brand and service
Different brands may affect the performance and quality of the lens. Under normal circumstances, the choice of well-known brands and good reputation of telecentric lens products can ensure product quality and after-sales service. Some brands may offer long-term warranties or have more authorized repair centers.
