Beam Expanders

Galilean type of Beam expansion
Ideal for laser processing application

Holmarc beam expanders provide accurate, unobstructed and achromatic expansion of any collimated input source and are easy to use. The most common type of beam expander is derived from the Galilean telescope which usually has one negative input lens and one positive output lens. The main advantage of Galilean design is that its overall length is smaller compared to a similar power Keplerian design.

Following Beam expanders are of the Galilean type and comes with M6 mounting holes. These are esay to mount and align using our standard posts and mounts.

Custom Beam Expanders

For automated applications, motorized beam expanders are available. With motorized systems, both expansion ratio and focus can be controlled independently from a remote location using control electronics and software. We also offer custom designed beam expanders for specific requirements. For further information on custom laser beam expanders, please contact us at sales@holmarc.com


Galilean type consists of a positive and a negative focal length lens.
