Beam Expander

Posted by Ningliu on May 13th, 2017

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 beam expanders, however, hardly 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 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.

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.
