An axicon, also known as a rotationally symmetric prism, is a lens that features one conical surface and one plano surface. They are commonly used to create a beam with a Bessel intensity profile or a conical, non-diverging beam. When converting a collimated beam into a ring, the plano side of the axicon should face the collimated source.

An axicon deflects light according to Snell's Law, which can be used to find the deflection angle:

Axicon Equation

where n is the index of refraction of the glass, α is the physical angle of the prism, and ß is the angle the deflected beam creates with the optical axis. Here, the refractive index of air is assumed to be 1. This interaction is illustrated in the reference image to the right. For more information, please see the Beam Shape tab above.

These precision-polished axicons are offered with base angles from 0.5° to 20°. These axicons are precisely manufactured from high-quality UV Fused Silica, making them ideally suited for high-power laser applications. Our axicons are offered uncoated or with an antireflection coating deposited on both sides for one of four wavelength ranges: -UV (245 - 400 nm), -A (350 - 700 nm), -B (650 - 1050 nm), or -C (1050 -1700 nm). These coatings reduce surface reflections from the lens to maximize transmission (Ravg < 0.5%). For a custom coating, please contact Tech Support for a quote.

Custom Axicons

Axicon Beams

  • Bessel Beam: Non-Diffracting
  • Ring-Shaped Beam: Ideal for Laser Drilling


Figure 1: The absolute value of a 0th order Bessel function. A true Bessel Beam requires each ring to have the same energy as the central peak, thus an infinite amount of energy is needed.

A Bessel beam is a non-diffracting beam of concentric rings, each having the same power as the central ring. Technically, a Bessel beam cannot be created as it requires infinite energy. A beam closely resembling a Bessel distribution can be generated by passing a Gaussian beam through an axicon and taking the projection of the beam close to the axicon’s conical surface. The absolute value of a 0th order Bessel function of the first kind is shown in Figure 1 (right).

When the beam is projected further from the lens, a single ring-shaped beam is formed. The beam is actually conical (i.e., diameter increases with distance), but the rays are non-diverging so that the thickness of the ring remains constant (see Figure 2). The ring's thickness will be half of the input laser beam's diameter. This type of beam is commonly used in laser-drilling applications.

Axicon Diagram

Figure 2: Axicon ray tracing diagram.

Apex Rounding

The intensity distributions of the resulting Bessel and ring-shaped Gaussian beams are influenced by tip imperfections. The central lobe of the zero-order Bessel beam shows intensity oscillations rather than spatial invariance1 if the tip is rounded, while the hollow Gaussian beam features an asymmetric ring with a tail towards the center or secondary rings2. To minimize apex rounding, Thorlabs manufactures axicons in-house. This allows for full control over the production process, resulting in a minimum apex rounding diameter of 0.70 mm.

Figure 3: Experimental setup for creating a hollow, ring-shaped Gaussian Beam.

Figure 4: Ring-shaped beams as seen on a viewing screen for the Thorlabs axicon (top) and two generic axicons (middle; bottom). The ring generated by the Thorlabs axicon transitions from high to low intensity over a short range, while the generic axicons make the transition over more pixels. The white horizontal line indicates the location of the extracted intensity profiles in the graph below.

Since any imprefections in the axicon tip will influence the properties of the output beam, we demonstrate the quality of our Thorlabs axicons by comparing the resulting hollow Gaussian beam to those produced by two generic axicons. The ring-shaped beam can be created by using the experimental setup shown in Figure 3, which includes a 633 nm laser, GBE05-A 5X achromatic Galilean beam expander, an SM2D25D SM2 ring-actuated iris, the axicon (AX2520 and two generic axicons with a physical angle of 20°), and an EDU-VS1 polystyrene viewing screen. For optimal performance, the laser incident on the axicon must have a collimated, small diameter beam. This is achieved by expanding a collimated beam and then passing the beam through an iris closed to 2.0 mm. The resulting beam shape is then projected onto the viewing screen, which is positioned in the far-field. For ease of translation, the screen was mounted onto a dovetail optical rail with a snap-on rail carrier. 

Figure 4 shows images of the resulting ring-shaped Gaussian beams visible on the viewing screen from the three tested axicons. Qualitatively, the Thorlabs axicon (Figure 4, top) produces a clean ring with high contrast between the ring edge and the dark center. The axicons from other manufacturers, however, produce rings of varying quality. One of the generic axicons, shown in the middle panel of Figure 4, produces a ring with poor contrast between the high and low intensity regions. The primary ring appears weak and there is visible, non-zero intensity within the ring. The second generic axicon, shown in the bottom panel, produces a clean ring with a subtly weaker contrast between the edge of the ring and the dark center.

To emphasize the intensity variations within the resulting beams, a false-color scale version of the images was generated and a line profile extracted. Figure 4 shows a side-by-side view of the original (left) and false-colored (right) images; a white line is included to show where the intensity profile was taken from and the corresponding pixel information is shown in Figure 5. A comparison of the line intensities from the three tested axicons shows that the Thorlabs' axicon has the sharpest intensity peaks, i.e. the best contrast, since the intensity goes from bright to dark over the lowest number of pixels. The generic axicons transition from a bright edge to a zero-intensity center over a larger range of pixels, which is visible in the slowly decaying tails of the asymmetric intensity peaks. This results in reduced contrast between the bright ring and hollow center. Please note that the non-zero peak at the center of the ring is an expected feature since only an ideal, perfect axicon will have high intensity edges and zero-intensity everywhere else. By improving the apex rounding diameter and reducing surface imperfections of the axicon, the contrast between the high intensity region and the nonzero center can be improved.

Figure 5: Line profiles extracted from the images of the ring-shaped beams in Figure 4. The Thorlabs axicon produces the sharpest intensity peaks, with the steepest transition from the bright edge to zero-intensity center. Intensity is presented in aribitrary units and is not an absolute measurement. Position is also provided in arbitary units, but is related to the pixel number.

Hello, thank you for contacting Thorlabs. I will have a representative from our office in China reach out to you about an appropriate format for this optical model.

We found that the center is not precisely machined. For small diameter initial beams (1 mm) the axcicon is more like a lens. I send you an e-mail to the tehnical department to have more news, but I did not received any answer. Could you try to contact them. Best Daniel Comparat

Response from Tim at Thorlabs: The rings could be a result from imperfections in the tip of the axicon, however, the quality of the tip of these optics are unrivaled in the industry and would make this an unlikely reason. Misalignment could contribute. Possibly you are seeing artifacts of the Bessel beam that is generated when a Gaussian beam is inputted. This is touched upon under the “Beam Shape tab on this page. We will work to improve the discussion on this page to better explain the performance of these parts and options you may have to achieve desirable results. We will contact you to troubleshoot this artifact in your setup.
totlab  (posted 2012-12-11 23:05:54.373)
We bought a axicon and found the ring is not so clean, and several smaller rings are in the inner side. The laser beam is collimated and dia=2mm. Is it because the imperfection of the tip of the axicon? I found no dust or damage on the surface.

Response from Javier at Thorlabs to info: Thank you very much for contacting us with your inquiry. Since axicons produce a ring-shaped beam, they work well for replacing the dark field patch stop in a dark field microscope. Although we have not yet developed an application in dark field microscopy using axicons, there have been several publications in this field. You can find one of these publications through the following link: http://spiedigitallibrary.org/jbo/resource/1/jbopfo/v13/i4/p044024_s1?isAuthorized=no

Would this be a good lens to use in a the light source path of a dark field microscope?
