Laser Beam Expander, Tunable, Dual wavelength, 800-400nm, X2 - X8

Manufacturer's part number :


Manufacturer Altechna


Description :

Dual wavelength 800-400nm tunable beam expander is Galilean type telescope with 2- 8X magnification, which allows compact design for using in industrial environment. It features lenses are air spaced, thus expanders are suitable for high power applications. Standard beam expanders are designed for four most popular lasers: Nd:YAG; Ti:Sapphire; Yb:KGW and Yb:YAG, but custom wavelengths are available. Standard mounting thread is M27x1, which is compatible with common 4-axis mounts.
