Description

The  5x Laser Beam Expander is a precision optical accessory engineered to enhance the performance of high-power laser systems. Designed for use with fiber lasers, pump lasers, and 1064nm wavelength systems, this beam expander increases beam diameter while reducing divergence, delivering a collimated, uniform output ideal for cutting, engraving, alignment, and research applications. Featuring ZEMAX optical optimization, high-quality coatings, and robust mechanical construction, it ensures exceptional optical clarity and durability.


Key Features

  • 5x Beam Expansion: Effectively expands laser beam diameter by a factor of 5 for reduced divergence and improved focusability.

  • ZEMAX Optical Optimization: Designed using advanced optical simulation software to minimize distortion and maximize performance.

  • Broad Compatibility: Suitable for 1064nm fiber lasers, pump lasers, and compatible with SMB905 interface (pre-installed).

  • Adjustable Focus: Allows fine-tuning via telescopic extension and rotational positioning for precise beam control.

  • Large Clear Aperture:

    • Eyepiece clear aperture: 16mm

    • Objective clear aperture: 36mm

  • High-Quality Optical Coatings: Anti-reflective coatings enhance transmission and reduce losses.

  • Durable Construction: Made from stainless steel or metal silver finish, with high mechanical strength and precision threading (M22×0.75).

  • Ideal Pairing: Optimized for use with 行者’s “至强” series high-power laser systems.
