To achieve collimated light, there are two theoretical methods: a) positioning an extremely tiny source precisely at a distance equal to the focal length of an optical system with a positive focal length or b) observing the point source from an infinitely distant location. In reality, neither of these situations is achievable. As well, according to diffraction theory, even if one of these conditions were met, there would still be a certain degree of spreading or divergence.

Aspheric lenses have a varying curve across the lens, whereas traditional lenses have a circular shape and could be part of a larger circle or sphere. Aspheric lenses tend to be thinner and flatter compared to their traditional lens counterparts.

The diagram below shows a beam of initial diameter x1 being shrunk to a final diameter of x2 and the distance between the two lenses is d. If we wanted to expand the beam, the plano-concave (negative focal length) lens would be placed first and have focal length f1, and the plano-convex lens would be placed second and have focal length f2.

Aspheres are often used to collimate light that is leaving a fiber or laser diode. The surface of an asphere is designed to eliminate spherical aberration, as spherical aberration is often what prevents a single spherical lens from achieving diffraction limited performance when focusing or collimating light for monochromatic sources.

Chromatic aberration of a single lens causes different wavelengths of light to have differing focal lengths, whereas an achromatic doublet brings red and blue light to the same focal point.

Achromatic lenses provide users with the ability to regulate the field of view, collection efficiency, and spatial resolution of their setup. They also enable the configuration of illumination and collection angles, which is beneficial for sampling purposes.

A collimator lens system, composed of a set of lenses, can be employed to create a collimated beam. In this method, the light source is situated at one end of the system, and the lenses are arranged in a way that they refract and concentrate the light, resulting in a parallel beam. This technique is commonly utilized in laser diodes, telescopes, and other optical devices that necessitate a collimated beam.

There are different types of lenses used to generate a collimated beam, each with their own disadvantages and advantages. We will discuss a few options below.

A collimated beam is light with weak divergence, meaning it’s a flow of photonics that move in parallel to one another, without dispersing. The beam remains concentrated in a specific direction, and its energy is evenly distributed along its path. This distinct characteristic of collimated beams makes them valuable in different industries, such as scientific research, engineering, and medical applications.

In this article we will discuss how collimated light beams are created, lenses and coatings that can be applied to manipulate a broad spectrum of wavelengths, and practical applications.

Machine Vision Systems are used for contactless detection and inspection of products in production environments. A Vision System often includes a camera and software. These are definitely necessary. But choosing a good lens, a suitable filter and the right light is just as important. The range in the Machine Vision Shop focuses mainly on these category of products. We have applied all products that you find in our range in the professional field ourselves. This knowledge enables us to optimally support you in finding the right combination for your application. In addition to our qualitative light, lenses and filters, we also offer two types of mounting brackets for fast and robust mounting of the components at the inspection position. We can't make it any easier for you.

Collimated beams find practical use in various fields such as scientific investigations, laser advancements, sensors, medical imaging, and industrial processes like laser cutting and welding.

Laser collimation

To collimate a diverging beam, we can use lenses with different focal lengths. The resulting diameter of the collimated beam increases as the focal length becomes longer. Assuming an initial tight focus and the subsequent expansion of the beam over a long distance, the distance between the focus and the collimation lens should be equal to the focal length. Using this information, the radius of the collimated beam can be determined by multiplying the half-angle of the beam divergence (or more precisely, its tangent) by the distance.

When light rays with a specific orientation hit the surfaces of either parabolic or elliptical mirrors, they create a bundle of reflected rays. This bundle converges at a single point known as the focus.

In the real world, light is collimated with a collimator device, which essentially is a lens or curved mirror where the focal length or curvature radius is chosen such that the originally curved wavefronts become flat. Of course, the beam radius at the position of the lens or mirror should be large enough to obtain a low divergence. Any residual divergence can be fine adjusted via the position of the lens or mirror along the beam direction. The collimation can be checked, for example, by measuring the evolution of beam radius over some distance in free space with certain kinds of interferometers.

To minimize divergence of a collimated beam, two factors must be balanced: focal length of the collimating system and size of the light source. The diagram below demonstrates the approximate divergence of a collimated beam:

Achromatic lenses are particularly good for collimating when a broad spectrum of wavelengths is present. They typically consist of two optical components cemented together, usually a positive low-index (crown) element and a negative high-index (flint) element.

An achromatic lens comes in a variety of configurations, most notably, positive, negative, triplet, and aspherized. It is important to note that it can be a doublet (two elements) or triplet (three elements); the number of elements is not related to the number of rays it can correct. In other words, an achromatic lens designed for visible wavelengths corrects for red and blue, independent of it being a doublet or triplet configuration. Below are diagrams outlining the four varieties of achromatic lenses.

Dayy Photonics offers fiber coupled light sources but also free space products with a collimated beam. We can customize our light sources to provide the desired beam diameters and minimum divergence angle.

Each type of plano lens has its specific properties and applications, making them suitable for different optical needs. Plano lenses are typically a cost-effective option when your minimum divergence specification can be relaxed, such as systems that do not require the beam to stay collimated for long distances.
