Reflective Beam Expander
PRODUCT CATEGORIES
INOUIRY
Reflective beam expanders are ideal for applications requiring broadband or achromatic beam expansion and a variety of light sources.
This series of beam expanders features a fully reflective design that can be used with a variety of lasers, including tunable, UV, and ultrafast sources, while their innovative design ensures high precision with minimal wavefront distortion.
Various integrated design elements, including reflective flats, threaded holes, and through holes, help simplify alignment and installation, and can be integrated into any laser application. The monolithic design ensures performance and stability, and is not affected by temperature changes.
Reflective beam expanders are available in 2x, 3x, 5x, and 8x magnifications with a variety of coating options for the UV, visible, and IR spectrum.
Beam Expanders Features:
HR coatings for UV, Visible and IR applications from 250nm to 10μm
Available in a wide range of reflectance magnifications from 2x to 8x
Monolithic design to reduce thermal effects
Beam Expanders Compatible Light Sources:
UV lasers (excimer, Nd:YAG, etc.)
IR lasers (Nd:YAG, CO2, quantum cascade, etc.)
Ultrafast lasers (Ti:Sapphire, fiber, etc.)
Tunable lasers (Ti:Sapphire, dye, quantum cascade, etc.)

Working Principle of Reflective Beam Expander:
The working principle of the reflective beam expander is based on the principle of total reflection. Light enters the beam expander through the reflector, focuses on one side of the lens, and then reflects the light to a smaller area. This focusing effect is due to the combined effect of the reflection of the HR-Beam Expander and the refraction of the lens.
