266nm 1X – 3X Research-Grade Variable Beam Expander

Product Details For optimal performance, center the laser beam to the entrance lens and ensure that the beam is parallel to the beam expander’s optical axis. 1X – 3X and 2X – 8X Variable Magnification Non-Rotating Lenses Minimize Beam Wander Compact Galilean Designs with Fixed Housing Length TECHSPEC Draconis Broadband Beam Expanders Also Available TECHSPEC Research-Grade Variable Beam Expanders (RVBX) are ideal for high power laser applications where magnification changes may be required, such as prototyping or R&D. TECHSPEC Research-Grade Variable Beam Expanders feature λ/4 transmitted wavefront, Galilean designs, and high laser damage threshold AR coatings to ensure maximum transmittance while minimizing ghost reflections. Additionally, these beam expanders use internal translation and focusing mechanisms to variable adjust magnification and laser divergence without affecting overall housing length. This compact design removes the need to make system accommodations for changes in length and eases system integration. TECHSPEC Research-Grade Variable Beam Expanders can be used to determine a system’s required beam magnification in the prototyping phase of development. TECHSPEC Draconis Broadband Beam Expanders are available for production or OEM implementation. Please contact our Sales Department for custom magnification requirements.
