Laser Beam Expander, Tunable, for Femtosecond Lasers, 266nm, X2-X11

Manufacturer's part number :


Manufacturer Altechna


Description :

Beam expander is design to expand or reduce collimated beam of light. 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. These beam expanders have been designed for use with Yb doped material, Nd:Glass, Er:Glass, Ti:Sapphire lasers and their harmonics.
