Review THORLABS 5x Uvfs High power Beam Expander V coated 1064 Nm

The Thorlabs BE03-1064 5X UVFS High-Power Beam Expander is an essential optics component designed for applications requiring the expansion of 1064 nm laser beams with high power. This beam expander is part of Thorlabs' UVFS (Ultra-Violet Fused Silica) product series, which is known for its high optical throughput, excellent surface quality, and superior damage threshold.

The BE03-1064 5X beam expander consists of five identical fused silica lens elements arranged in a telescopic configuration. Each lens element has a focal length of 100 mm, resulting in an overall magnification of 5X. The lens surfaces are precision-machined and polished to ensure flatness within /50 at 632.8 nm and surface roughness below /10 at 632.8 nm. This level of surface quality and flatness guarantees efficient beam expansion with minimal distortion and aberrations.

The beam expander is designed to be compatible with 1064 nm lasers and other infrared sources. The lens elements are V-coated with a high reflectivity coating for the 1064 nm wavelength and an anti-reflective coating for the visible and near-infrared wavelengths. This coating combination ensures optimal transmission for the laser beam while minimizing reflections that could lead to signal loss or unwanted interference.

The BE03-1064 5X UVFS High-Power Beam Expander is designed to handle high power laser beams. Its fused silica lens elements have a high damage threshold, making it suitable for use with high-power 1064 nm lasers. The lens elements are also thermally stable, ensuring that the beam expander maintains its optical performance under varying temperatures.

The beam expander comes with a CAD model available for easy integration into custom optical systems. It is also compatible with standard 35 mm threaded optics mounting, making it easy to integrate with other optical components. The small form factor of the beam expander, combined with its high power handling capability and excellent optical performance, makes it an ideal choice for applications that require efficient beam expansion of high-power 1064 nm laser beams.
