These lenses are used in microscopes instead of the usual microscope objective lenses. They have an adjustable working distance through a focus ring that adjusts the working distance for magnification. This comes at the cost of slightly losing telecentricity.

Telecentricity is achieved by setting an appropriate aperture within the lens’s exit, entrance, or both. Incidentally, the type of telecentric lens is defined by the configuration of its appropriate aperture.

These types of lenses are the more expensive and larger variety of telecentric lenses. This is mainly because they have to be at least as big as the biggest object they have to capture. This often makes for more components to attain telecentricity.

The applications of telecentric lenses are plenty across multiple disciplines of the industry, mainly in automated labor. They are a vital component of machine vision technology. This tech enables machines to “see” and process their work and accomplish their designated tasks.

In industries or fields of study that demand the capabilities of precise measurement through telecentricity, they are the only choice of lens. Their use is a non-compromisable decision. Therefore, the discussion of choosing conventional lenses over them is moot.

They may be costly but will be worth all that money in applications that strictly require telecentricity – something that only they can deliver.

Any task that will benefit from telecentricity and the properties it brings to the table will benefit from using telecentric lenses.

Telecentricity is achieved when one or both ends of a lens have an appropriate aperture. These lenses provide an image that sidesteps parallax error due to light angle incidence and image magnification. This means the image you acquire through them is the most accurate 2-dimensional representation of objects.

If an appropriate aperture is affixed to both the entrance and exit, they are classified as bi-telecentric lenses. Wide uses of these range from optics to metrology.

Objects with these lenses may appear sharp or blurry depending on the object’s distance from them, but every object will be of the same size despite the difference in distance.

The object-space telecentric lenses have their entrance pupil set to infinity by an appropriate aperture. This makes for them to produce an orthographic projection.

The bi-telecentric lens has both its entrance and exit pupils set to infinity by two appropriate apertures set on each end. This type of telecentric configuration allows for more accurate measurements than that of mono-telecentric lenses.

What makes a lens telecentric is a lens’s ability to produce an orthographic image via a pupil (entrance or exit) that has been set to infinity or unlimited distance. Where normal lenses produce an image skewed by parallax or perspective error due to their defined focal length, telecentric lenses always give a definite perception of an object.

These lenses are naturally afocal due to the collimation of the object’s image formed by the first appropriate aperture by the second appropriate aperture.

These types of lenses operate at a fixed working distance, meaning objects within the fixed working distance will appear sharp and in focus, while objects that are outside the working distance will appear out of focus and blurry.

Exit-situated appropriate aperture lenses, or image-space telecentric lenses, will produce images of an object regardless of its distance from an image sensor.

They are classified by where a fixed aperture is situated. Entrance-situated appropriate aperture lenses are called object-space telecentric lenses. These produce orthographic images of objects. These kinds may have a fixed working distance or may also come with a focus ring.

Applications of these type of lenses include optical lithography, where light is used to make super thin patterns on materials like silicon wafers.

The image-space telecentric lens has its exit pupil set to infinity by an appropriate aperture. This configuration produces the same-sized images regardless of the distance between the object and an image sensor.

Examples of these lenses are some microscopes. How do microscope lenses work? Microscope lenses are normally objective lenses. A microscope objective lens or its microscope objectives collect light from the sample to image a subject through a high-powered magnifying glass and a short focal length.

The clearest advantage would be how they eliminate the parallax or perspective error. And their more obvious disadvantages pertain to their cost.

The objects which do not have light of their own and shine in the light of other luminous objects are called illuminated objects.

A telecentric lens is a type of optical lens that has an infinity for both or either its entrance or exit pupil. These lenses are important for Industry applications that specifically demand perfect precision with two-dimensional measurements. Telecentric lenses are effective in imaging objects that are subject to size distortion due to light incidence angles or image magnification.

Applications for these lenses include conditions that are sensitive to the angle of incidence, where the focus is vital not just from the center of the image but also in its periphery. An example of this would be image sensors that involve microlens arrays, like in digital cameras.
