OPTO Telecentric Lenses
Opto Engineering produces several telecentric lens series, each with specific features and applications
Opto Engineering offers a wide range of telecentric lenses designed for machine vision applications where precise, accurate, and distortion-free measurement is essential. These lenses are designed to prevent the perspective error, or parallax, that typically occurs when imaging three-dimensional objects.
Telecentric lenses are Opto Engineering’s core business: they are the result of over twenty years of constant investment in R&D. Not only do we design and manufacture a wide range of models, we hold numerous international patents. We have received awards and prizes in the machine vision sector, and are universally known as THE TELECENTRIC COMPANY®, our trademark combined with the blue ring trademark used on all our telecentric lenses.
Telecentric lenses are used in innumerable vision applications, and in particular they form the critical component of the optical system when precise measurement is required. Non-contact measurement applications demand the use of such lenses which, thanks to their low distortion, can eliminate perspective errors (parallax effect) due to imprecise positioning or objects with strongly 3D geometries.
Opto Engineering offers a vast range of precision telecentric and bi-telecentric lenses for the most diverse requirements of the market: models for high and low resolution area and line scan sensors in a variety of magnifications and working distances; classic, compact and flat lenses, along with standard and custom solutions.
Key features
Constant magnification
An object’s size and shape appear consistent throughout the field of view, even if it moves closer or farther away from the lens. This is the main advantage of telecentric lenses and a crucial feature for accurate measurement.
Low distortion
Reduced parallax error
Enhanced depth of field
High resolution
Telecentric lenses can achieve excellent resolution, which is vital for inspecting small and intricate objects.
Typical applications
Machine vision systems
Metrology
Essential for highly accurate part measurements in manufacturing and lab environments, with applications including precision mechanical parts like engine components, screws, and springs.
Semiconductor and PCB inspection
Helps detect defects and inspect components on microchips and circuit boards.
Pharmaceuticals and packaging
Used for inspection tasks like verifying label positioning, seal integrity, and fill levels.
360° view lenses
The company also produces special lenses for inspecting cylindrical objects from all sides, which can reduce the number of cameras and lenses needed.
