We offer a variety of Laser Beam Expanders to suit most laser types, from small waveguide lasers up to multi-kilowatt industrial lasers. There is also a modular range for experimental and laboratory
purposes. The most common type of Beam Expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The input lens presents a virtual beam
focus at the output. For low expansion ratios (1.3-20 times) the Galilean telescope is most often employed due to its simplicity, small package size and low cost.
