Beam Expanders

Safeguard the ti-Series laser on your production line with extra protection from dirt, dust and processing vapors with a Synrad BE-300, BE-400 or BE-500 beam expander.

Small, lightweight and easy-to-install, our BE-Series Beam Expanders expand and collimate the beam diameter of your laser's output by 3x, 4x or 5x, to reduce or eliminate damaging hot-spots and optics damage that can sometimes occur in harsh operating environments.

Ruggedly constructed from a single aluminum block and anodized for added corrosion resistance, BE Beam Expanders conveniently and easily mount to the front of ti-Series lasers via slotted holes on the input face for maximum adjustability and perfect alignment. O-ring gaskets on both ends of the unit ensure a snug fit and fully airtight seal between the expander and the laser, and between the expander and any other optical components mounted to the threaded 8-32 UNC holes on the output face of the expander.

The interiors of BE-Series Beam Expanders are fully shielded from the operating environment, and conform to IP6 standards. Two ZnSe Galilean telescopic lenses ensure maximum transmission of laser power.
