18 Inch Beam Expander (BEX)

Swapped out our old unit and the fit was exact, no shimming or adapters needed. The Standard configuration mates up cleanly with our existing mounts, so the install took under an hour. Solid build, exactly what the lab needed for the 18-inch setup.

Installed this 18 inch beam expander on our interferometer setup and the standard configuration aligned perfectly with our existing mounts. The optics are exceptionally clean and the beam expansion is uniform across the full aperture.

Installed this on our test bench and the alignment held steady through multiple thermal cycles. The 18-inch aperture is exactly what we needed for our Zygo interferometer setup.
