BE02M-A - 2X Optical Beam Expander, AR Coated: 400 - 650 nm  Features 2X Beam Expansion or Reduction 3 Broadband AR Coating Wavelength RangesA: 400 - 650 nm B: 650 - 1050 nm C: 1050 - 1650 nm Sliding Lens Adjustment that Minimizes Beam Walk Off Housing with Fixed Mechanical Length and Non-Rotating Ends Collimation Adjustment Ring can be Locked with Included Hex Key Can be Used to Reduce Beam Size by Using the Larger Aperture as the Input Threaded Apertures for Integration into Optical Systems Thorlabs' Achromatic AR-Coated Galilean Beam Expanders can expand or reduce the diameter of a collimated beam by a factor of 2, 3, 5, 10, 15 or 20.  These beam expanders use a low-aberration, achromatic design optimized to provide a wavefront error of less than ?/4 (i.e., diffraction-limited performance) and minimize the impact on the M? value of the expanded beam. An expanded beam can be focused to a narrow diffraction-limited waist, which can be necessary for use with optics or instruments that have small input apertures such as Fabry-Perot interferometers.
