Beam Steering with Galvos: Common Configurations and Their Uses

[@eugene9294]

Are you familiar with systems with focusing after galvano scanners? I need to scan the laser beam at a distance of 500-1000 mm from the galvano scanner (with the ability to change the beam focus within 50-100 mm).

Thank you for your question! It sounds like you are describing a post-objective scanning system similar to our XG330 and DCB320, which can be found here: www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=14125 For more information about 2- and 3-axis systems, you can read our brief overview here: www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=14125&tabname=2-Axis%20vs.%203-Axis If you have more in-depth questions about your setup or application, feel free to reach out to us at [e-mail].

@@thorlabs I consider such a system as an alternative. I was talking about the system: a parallel laser beam from the scanner hits a plano-convex lens (the convex part is up), laser beam converges in focus, then diverges and hits another plano-convex lens (the convex part is down), after which the parallel beam hits a focusing double convex lens. The first lens is mounted on a movable table to allow changing the focus.
