Laser Beam Delivery Components

Motorized Variable Beam Expander

Overview

The Motorized Variable Beam Expander (MVBE) allows for remote adjustment of laser beam diameter and divergence. Each unit includes internal focusing optics driven by a compact servo system, making it easy to dial in beam characteristics without manual intervention. These expanders are ideal for dynamic laser systems, R&D setups, or production lines where fine-tuning beam size is required for different materials or processes. Available in multiple aperture sizes and mounting options for seamless integration into Haas or third-party beam delivery systems.

Applications

Motorized variable beam expanders are used in systems where remote control over beam size and divergence is essential. Common applications include:

  • Laser processing systems where different materials or operations (e.g., cutting, welding, engraving) require on-the-fly adjustments to beam size.

  • Automated production environments where manual optical adjustment is impractical or too slow.

  • R&D labs working on variable process development or tuning laser spot sizes across a wide range of parameters.

  • Optical test benches requiring repeatable adjustments in beam divergence for alignment or measurement tasks.

These components may also be referred to as motorized beam collimators, remote beam expanders, or servo-adjustable beam expanders, all of which are supported by this series.

Selecting a Part Number

To select the appropriate Motorized Variable Beam Expander (MVBE), follow these steps:

  1. Select the aperture size
    Choose the aperture size that matches your beam delivery system:

    • 19mm, 25mm or 50mm

  2. Select the wavelength
    Choose the wavelength range compatible with your laser:

    • Depending on the aperture size selected, it may be a one size fits all or you may need to specify the wavelength

  3. Select the translation type
    Choose how the internal optics are adjusted:

    • S for Manual

    • M for Motorized
