Laser Beam Expanders.. In the design of a laser beam expander, the objective and image lenses are reversed.. In a Keplerian beam expander the input beam is focussed to a point between the two lenses.. This creates a spot of concentrated energy within the beam expander which heats the air within the system and deflects light from it’s optical path..
Small, lightweight and easy-to-install, our BE-Series Beam Expanders expand and collimate the beam diameter of your laser’s output by 3x, 4x or 5x, to reduce or eliminate damaging hot-spots and optics damage that can sometimes occur in harsh operating environments.. Highlights External Link Pop Up.. Rugged construction.. Conforms To IP6 Standards..
R 1 = radius of curvature of entry lens.. h 2 = radius of exit spot (image height) h 1 = radius of entry spot (object height) The spacing, t, between the two lenses will be equal to the sum of the focal length of the lenses.. t = f1 + f2.. A beam expander can be used in reverse, with the larger diameter lens as the input and the smaller diameter ..
Laser-beam expanders Objective: In this lab students will build two laser-beam expanders.. The output of a laser is different than that of most other light sources.. The laser resonator determines the spatial characteristics of the laser beam.. Most lasers have spherical-mirror Fabry-Perot resonators that have Hermite-Gaussian spatial modes..
The beam expander 1x-8x is part of the Silverline TM high-power lens series and is designed for laser applications in wavelength ranges of 355 or 1030–1080 nanometers.. The optical system of the objective lens is designed in such a way that a diffraction-limited image quality is achieved across the entire expansion range..
Beam expanders are optical devices that take a collimated beam of light and expand its size (or, used in reverse, reduce its size).. In laser physics they are used either as intracavity or extracavity elements.. They can be telescopic in nature or prismatic.. Generally prismatic beam expanders use several prisms and are known as multiple-prism ..

The product of beam diameter and divergence of the laser beam is a constant and therefore remains unchanged, i..e.. increasing the beam diameter means reducing the divergence of the beam to the same degree.. This is true for the expanders with fixed expansion factor as well as for the zoom expanders, where the magnification is variable..

The Expander works with all Spyder 3 lasers, but let's take the Krypton as an example.. At a range of 500 meters, the Krypton's beam diameter is 750mm – already pretty small.. With the Expander, the Krypton's beam diameter is just 95mm, allowing for pinpoint targeting and a lot more possibilities to utilize your laser's power.. Zero In
