The BZ series of Zoom Variable Beam Expanders are available with 2X - 8X continuously variable beam expansion ratio. For the zoom models, the expansion ratio can be adjusted from the minimum to the maximum value via one full rotation of the zoom control. Once the desired magnification is obtained, a setscrew can be tightened to lock the magnification.
Our Zoom Variable Beam Expanders include the working wavelength 9.6um, CO2 10.6um, YAG 1064nm, 532nm, 355nm.
