Zoom beam expanders correct for laser-beam divergence

Edmund Optics has introduced its new Zoom Beam Expander. The compact Zoom Beam Expander is designed primarily for Nd:YAG (1064, 532, and 355 nm) and 800 nm laser sources. It provides variable magnification of 1x to 3x and 2x to 8x with adjustable focus to correct for laser-beam divergence.

The antireflective coating can be customized for a variety of wavelengths. The zoom feature allows the user to change beam expansion powers (the size of the output beam relative to the input beam), which allows users to optimize system performance without holding a large inventory of various fixed beam expanders, saving time and money, and allowing system flexibility in research and industrial settings.

Edmund Optics Introduces Zoom Beam Expanders
Variable magnification of 1-3X and 2-8X
corrects for laser beam divergence

Edmund Optics (EO), the premier provider of optical components, introduced their new Zoom Beam Expander. The compact Zoom Beam Expander is designed primarily for Nd: YAG (1064 nm, 532 nm and 355 nm) and 800 nm laser sources. It provides variable magnification of 1-3X and 2-8X with adjustable focus to correct for laser beam divergence.

Ideal for high power laser applications
Edmund Optics' Zoom Beam Expanders are designed and tested for high power laser applications at a specified wavelength. Damage threshold rated for high power lasers, they are ideal for materials processing applications. The Anti-reflective coating can be customized for a variety of wavelengths.

Zoom feature provides system flexibility
The zoom feature allows the user to change beam expansion powers (the size of the output beam relative to the input beam). This is ideal for system integrators using multiple laser vendors with a fixed optical train platform. Using the zoom feature, the user may adjust the laser beam size to optimize system performance without holding a large inventory of various fixed beam expanders, saving time and money, as it allows system flexibility in both research and industrial settings.

Numerous Magnification/Output Clear Apertures available at a variety of wavelengths
The zoom assembly features fine thread for smooth rotation. Edmund Optics' Zoom Beam Expanders are available for 1064 nm lasers in both 1-3X and 2-8X models, with Output Clear Apertures of 20 mm, 30 mm, 38 mm and 60 mm. The 800 nm model has a variable magnification of 2-8X and an Output Clear Aperture of 30 mm. Models for 532 nm are available with variable magnification of 1-3X with an Output Clear Aperture of 20 mm and with variable magnification of 2-8X with Output Clear Apertures of 30 mm and 60 mm. The 355 nm models with variable magnification of 2-8X are available with Output Clear Apertures of 30 mm or 60 mm. Edmund Optics' Zoom Beam Expanders are in-stock and available for immediate delivery.
