( Brand: Thorlabs ), ( Unit Type: Unit ), ( Manufacturer Part Number: BE03-355 )
The Thorlabs BE03-355 is a versatile 3x high-power beam expander designed for use with UV and visible light applications. This expander features an all-glass design with three fused silica rods for excellent beam quality and minimum insertion loss. With a beam diameter increasing up to three times the input diameter, it is ideal for applications that require coupled power enhancement with minimal beam distortion.
The BE03-355 is constructed from high-quality optical components, ensuring excellent imaging performance and stability. It features a flat and uniform output surface, ensuring optimal energy distribution and maximizing the efficiency of your laser system. This expander is designed to work with a wide range of input beam diameters, from approximately 1.2 mm to 4.5 mm, making it a perfect solution for various lasers and applications.
The BE03-355 is designed for high power applications with a thermal load capacity of up to 35 W (continuous, average power) and a peak power handling capability of up to 6 kW. The expanders are optimized for use with short-pulse lasers, and the fused silica rods provide superior damage threshold and sufficient thermal stability. The expanders are also compatible with narrow bandwidth lasers as the highest Fourier frequency is significantly smaller than 0.355 m.
The BE03-355 comes in two separate components, a beamsplitter and a pair of expanding rods, allowing for easy and flexible integration into laser setups. The beamsplitter offers excellent reflectivity, ensuring minimal loss of the incident beam. The high-quality optical surfaces of the components are protected by removable anti-reflection coatings. The expanding rods have threaded ends that can be easily secured to the user's setup with included setscrews.
The robust design of the BE03-355, including the rugged anodized aluminum housing and the integral heating and cooling system, offers a long service life and stability under various environmental conditions. Thorlabs' high-power beam expanders are backed by a comprehensive two-year warranty, ensuring user satisfaction and a reliable and efficient optical solution.
