Beam Expander

  • Introduction

Beam expansion


Beam expansion or reduction is a common application requirement in most labs using lasers or light sources and optics. Users always find there are so many off-the-shelf laser beam expanders, however, hard to find one exactly fit their needs in terms of spectral range or expansion ratio. In most cases, the plug and play solution may not be the answer.


Hyperion Optics helps customers with their unique expander

Hyperion Optics helps customers with their unique expander development project, from optical design, mechanical design and responsible for the application performance. It is critical to communicate with our engineers your input and output beam diameter ratio requirement. For simple expanders, such as telescopes, consists of two lenses, the magnification of a 2 lens system is equal to the ratio of the focal lengths of the lenses, which is also equal to the ratio of the radii of curvatures of the lenses.

unique expander for sale


M= the magnification of the beam expander

F2= effective focal length of exit lens

F1= effective focal length of entry lens

R2= radius of curvature of exit lens

H2=radius of exit spot (image height)

H1=radius of entry spot (object height)


At Hyperion Optics, we offer rapid optical design and prototyping, in most expander cases, we offer 6 weeks delivery, means when we study your application, expansion ratio and input output parameters, we are able to deliver assembled expander within 6 weeks. Or we can work on your existing off-the-shelf solution to improve your application’s performance.


We also offer off-the-shelf expanders, please refer to following products for your requirement, or contact our engineer for further information.

Details

The types of beam expander:

The beam expander can be divided into fixed beam expander and adjustable beam expander.

The principle of beam expander:

To Diffract and to change the laser beam diameter as well as divergence angle.

The function of beam expander:

The beam expander can change the diameter of laser and lens assembly of divergence angle.

The laser beam emitted from the laser has a certain divergence angle. For the laser processing, only by adjusting the beam expander, the laser beam can be changed into collimated (parallel) beam, and the fine resolution high—density facula can be obtained by using the focusing mirror.

How to use beam expander:

The most commonly used types of beam expander are traced back to Galilean telescope, which generally includes an input concave lens and an output convex lens. The input lens to transmit a virtual focal beam to an output mirror. People usually use telescopes design by Kepler when they need space filtering or large magnification. The Kepler telescope generally has a convex lens as the input lens, which sends the focused beam to the output element. In addition, spatial filtering can be achieved by placing holes in the focus of the first lens.
