Beam Delivery Devices – Extended Category Description

Beam delivery devices are essential optical components that guide, shape, and control laser beams between the source and the target. They ensure that a laser beam reaches its intended application point with the required size, divergence, stability, and intensity. Optogama provides a wide range of beam delivery devices designed for different spectral regions, from UV (Ultraviolet) to NIR (Near-Infrared), optimized for laboratory, industrial, medical, and defense applications.

These devices include beam expanders, beam reducers, and laser power attenuators. They help users adapt a single laser system for different tasks such as material processing, spectroscopy, medical diagnostics, metrology, defense technologies, and scientific experiments.

Main Product Types

Laser Beam Expanders

Beam expanders increase or decrease the laser beam’s diameter. By changing the beam size, users can control divergence and focus properties.

  • Compact Motorized Expanders (MEX, MEX-V2) – Motorized units with sliding-lens design, ensuring high pointing stability and precise divergence control. Suitable for dynamic laboratory setups and automated systems.
  • High-Power Expanders (MEX-HP) – Specially designed to handle HP (High-Power) laser systems without compromising optical quality.
  • Fixed Ratio Expanders (FEX) – Provide a constant magnification or reduction factor, ideal for applications that require stable and predictable beam shaping.
  • Variable Expanders and Reducers (VEX/VRE) – Allow adjustable magnification across a range, useful for systems requiring flexible beam tuning.

Applications:

  • Research labs (beam conditioning for experiments)
  • Micromachining and material processing (beam focusing)
  • LIDAR and remote sensing (beam divergence control)
  • Medical optics (precise beam shaping)

Laser Power Attenuators

Attenuators reduce the intensity of a laser beam without changing its wavelength, divergence, or spatial profile.

Applications:

  • Laser safety (controlling output intensity before entering experimental setups)
  • Medical lasers (adjusting dosage and energy delivery)
  • Spectroscopy (preventing detector saturation)
  • Defense and aerospace (stabilizing beam power under varying conditions)

Key Advantages of Optogama Beam Delivery Devices

  • Broad Spectral Coverage (UV–NIR): Support for wavelengths from ~250 nm (UV) to 2000 nm (NIR).
  • SWaP-optimized: Compact size, low weight, and efficient power use for portable and aerospace systems.
  • High Stability: Sliding-lens designs and precision mounts ensure reliable operation.
  • OEM Integration: Devices are built for direct use or easy integration into third-party equipment.
  • Flexibility: Wide choice between fixed, variable, manual, and motorized solutions.

Other Common Applications

While typically used in scientific laboratories, industrial machining, and defense, beam delivery devices also find growing use in:

  • Laser communication systems – ensuring proper beam alignment and divergence control.
  • Medical imaging and therapy – where precise power and beam shaping are critical.
  • 3D printing with lasers – controlling beam size and intensity for high precision.
  • Environmental monitoring – improving sensitivity of remote spectroscopy setups.
