Telecentric Lenses
Avantier Telecentric Lenses are precision-engineered optical components designed to deliver constant magnification, minimal distortion, and unmatched measurement accuracy. Unlike conventional lenses, telecentric lenses maintain a parallel chief ray path, ensuring that image size remains consistent regardless of object distance.
This optical stability makes them indispensable in machine vision, metrology, and industrial inspection systems, where even slight perspective errors can affect dimensional accuracy.
Avantier offers a complete range of object-space, image-space, and bi-telecentric lenses designed for demanding environments—from high-speed manufacturing lines to the extreme conditions of space. Each lens is manufactured and tested in-house for optical precision, mechanical robustness, and long-term reliability.
Key advantages include:
- Constant magnification and non-angular field of view
- Symmetrical depth of field and distortion-free imaging
- Exceptional stability across temperature and distance variations
- Configurable working distances and interfaces
- Proven reliability in industrial and aerospace applications

Avantier Telecentric Design Principles
Avantier Telecentric Lenses and Working Distance
Telecentric geometry allows imaging over long working distances without introducing parallax or scale error. This makes it ideal for automation lines or robotic inspection stations where space and access vary.
Telecentric Lenses vs. Conventional Lenses
Conventional lenses project angled rays that distort object scale as distance changes. Telecentric designs eliminate that effect, providing a flat, true-to-scale field ideal for high-accuracy measurement.
Bi-Telecentric Lenses
By combining object-space and image-space telecentricity, bi-telecentric lenses maintain uniform magnification across both fields — essential for metrology, wafer inspection, and scientific imaging.
Optical Efficiency and Distance Compensation
Avantier’s telecentric systems maintain constant ray parallelism, minimizing aberrations and ensuring image sharpness even when the object-lens spacing shifts slightly.
Technical Resource
What Are Telecentric Lenses?
A telecentric lens is a specialized optical system designed to maintain constant magnification, regardless of object distance. It achieves this by positioning its aperture stop (which determines the entrance or exit pupil) at or near infinity.
These lenses are essential in industrial imaging, metrology, and machine vision, where accurate two-dimensional measurements are required. They eliminate size distortions caused by varying light incidence angles or perspective, providing images that are true to scale.
How Telecentric Lenses Work
A lens becomes telecentric when its optical design produces an orthographic projection—that is, parallel chief rays across the field of view.
In a standard lens, magnification changes with object distance, leading to perspective (parallax) errors. Telecentric lenses correct this by using a stop position that makes either the entrance, exit, or both pupils appear to be at infinity, resulting in uniform magnification.
Types of Telecentric Lenses
Telecentricity can be achieved in three configurations, depending on where the aperture stop is placed:1. Object-Space Telecentric Lenses
In these lenses, the entrance pupil is located at infinity. This ensures the chief rays entering the system are parallel to the optical axis, resulting in an orthographic image.- Objects appear at a constant scale, regardless of distance within the depth of field.
- Focus remains sharp only at a fixed working distance; objects outside it become blurred, but their apparent size remains unchanged.
- Because they must be at least as large as the object they image, these lenses are typically larger and more costly.
2. Image-Space Telecentric Lenses
An image-space telecentric lens has its exit pupil at infinity. This means the chief rays exiting the lens are parallel, producing an image that remains the same size on the detector regardless of small shifts in image-plane position. This configuration is ideal for image sensors with microlens arrays, such as those used in digital cameras or line-scan sensors, where the angle of incidence affects pixel response.3. Bi-Telecentric Lenses
Bi-telecentric lenses combine both designs: the entrance and exit pupils are located at infinity. This creates telecentricity in both object and image space, maintaining constant magnification and illumination uniformity. Because both chief ray bundles are collimated, these lenses are afocal and offer the highest measurement accuracy. Applications include optical lithography, semiconductor inspection, and high-precision coordinate measuring systems.Advantages and Limitations of Telecentric Lenses
Pros
- Elimination of parallax error – Magnification remains constant across object depth, eliminating perspective distortion.
- Accurate dimensional measurement – Ideal for applications requiring repeatable geometry.
- Superior image uniformity – Reduced aberrations and vignetting create more symmetrical, distortion-free images.
Cons
- Higher cost – More complex optical and mechanical designs make them more expensive than conventional lenses.
- Larger physical size – Especially for object-space telecentric designs, where the front element must cover the entire field of view.
Summary: Why Telecentric Lenses Matter
Telecentricity is achieved by positioning one or both pupils at optical infinity, creating a system that removes the effects of parallax and magnification change.
- Object-space telecentric lenses provide orthographic projection with constant magnification, ideal for dimensional measurement and inspection.
- Image-space telecentric lenses ensure image size consistency on detectors, critical in imaging systems using microlens arrays.
- Bi-telecentric lenses combine both benefits, offering the highest precision and illumination uniformity across the field.
Beyond industrial and metrology uses, telecentric lenses are increasingly vital in space and aerospace missions, where optical stability and geometric accuracy are essential under extreme conditions.
In satellite-based metrology, optical navigation, and space telescopes, telecentric systems maintain constant magnification despite temperature swings, vacuum conditions, or vibration during launch. Their athermal and radiation-hardened designs prevent focus drift and image scaling errors that can compromise instrument calibration in orbit.
Modern missions such as Earth-observation satellites, planetary mapping instruments, and astronomical telescopes rely on telecentric optics to ensure that the data captured in microgravity remains spatially accurate over months or years of operation. These same principles of telecentricity—constant geometry, uniform illumination, and minimized aberration—make them invaluable for spaceborne imaging payloads where precision cannot be recalibrated once deployed.
Though more expensive and often larger than conventional lenses, telecentric lenses remain unmatched in dimensional stability, measurement accuracy, and optical reliability. From factory floors to orbital platforms, they provide the geometric consistency that defines modern precision imaging.
Conclusion
From precision factory inspection to orbiting observatories, Avantier telecentric lenses deliver constant magnification, exceptional optical quality, and enduring stability.
