BeamEx1000 beam expander enables measurement of full 6”aperture with industry-standard 4” interferometers.

Boynton Beach, FL ¬— Tower Optical announces the availability of a 4”→ 6” Interferometer Beam Expander called the BeamEx1000. This product enables measurement over a full 6”aperture using an industry-standard 4” interferometer. The BeamEx1000 snaps onto a 4” mainframe interferometer and accommodates an industry-standard 6” reference optic. Tower also offers a 6” reference transmission flat, TX-6, compatible with the BeamEx1000 beam expander and other 6” interferometer mounts.

The 4” Fizeau interferometer with bayonet mount has become an industry standard. Several companies offer versions; all have mutually compatible bayonet-mount interfaces for reference optics. Tower’s Beam Expander coupled with a 6” Reference Transmission Flat more than doubles the available test area, in mere seconds, at a small fraction of the cost of a larger-aperture The internal optics of the BeamEx1000 expand and re-collimate the beam to 6” diameter. Its output side includes a tip-tilt adjustment and a bayonet mount designed to fit available 6” reference optics, both flat and spherical.

The BeamEx1000 is available from stock for $6995. The optional TX—6 Transmission Flat is also available from stock for $4250. Contact Tower Optical at sales@toweroptical.com, or 1-561-740-2525. Detailed data is also available at www.toweroptical.com.
