    Reflective beam expanders exhibit significant utility in applications requiring broadband or achromatic beam expansion, accommodating a wide spectrum of light sources. The all-reflective configuration enhances versatility, enabling compatibility with various lasers, including tunable, ultraviolet, and ultrafast sources. The innovative design not only broadens the range of usable lasers but also guarantees elevated recision while concurrently minimizing wavefront distortion.
