The LBTEK 1X-4X variable magnification laser beam expander optical element is made of ultraviolet fused silica (UVFS). It is optimally designed for diffraction limits and the lens group adopts a Galilean structure without an internal focus, meeting the application requirements of most scientific research and industrial scenarios. The beam expander can be installed in the optical system by clamping components and is locked using a screw lock mechanism. The standard working wavelengths are 355 nm, 532 nm, and 1064 nm, and it can adjust the magnification of the incident laser beam size from 1X to 4X.

※ The new and old versions have been updated, with improvements in optical coating and mechanical knob damping feel.

※ The clamping outer diameters of LZBE-355-1-4X, LZBE-355-1-4X-B, and LZBE-532-1-4X-A are Ø41 mm, while the clamping outer diameters of LZBE-532-1-4X and LZBE-1064-1-4X are Ø37.6 mm (please select the corresponding clamping outer diameter fixture).

※ The laser beam expanding frame (Ø41 mm) is expected to be available in November 2026.

The LBTEK 2X-10X variable magnification laser beam expander optical element is made of ultraviolet fused quartz (UVFS). It is optimally designed for diffraction limits and the lens group adopts a Galilean structure without an internal focus, meeting the application requirements of most scientific research and industrial scenarios. The beam expander can be installed in the optical system by clamping, using a screw lock mechanism. The standard product has working wavelengths of 355 nm, 532 nm, and 1064 nm, and can adjust the magnification of the incident laser beam size from 2X to 10X.

※ The new and old versions have been updated, with improvements in optical coating and mechanical knob damping feel, etc.

※ The outer diameter of the clamping is Ø37.6 mm (please select the corresponding clamping outer diameter for the clamp)

The LBTEK Laser Beam Expander Mount is specifically designed for use with the LZBE series of variable magnification laser beam expanders, which can be fixed to a breadboard or optical table. To install this series of beam expanders, you need to pass through the inner ring of the mount to install them. The top lateral locking screw can elastically deform the mount to lock the mount without damaging the tube due to the screw being too long during installation. The mount has an M4 tapped mounting hole at the bottom, which can be supported by a Ø12.7 mm stainless steel optical post or other connector. A 3.0 mm hex key is included for locking.

LBTEK Laser Beam Expander Adapters are suitable for mounting and adapting LZBE series variable magnification laser beam expanders. They can be adapted to optical components such as adjustment mounts, coaxial systems, etc. with Ø2" light wall holes or SM2 tapped holes. The clamped part is fixed and mounted with an M4 rubber head set screw on the side to prevent the clamped part from rotating and sliding, ensuring that the center of the clamp is aligned with the optical axis. The M4 rubber head set screw can be adjusted and locked with a 2.0 mm hex key.
