Diffractive Optical Element (DOE)
Description:
LD Collimators & Diffractive Optics: Beam-Splitter
Diffractive beam splitters excel in applications requiring precise control of light beams, compact and lightweight design, wavelength specificity, high efficiency, and versatile beam pattern generation. They are particularly valuable in laser systems, optical metrology, display technology, and spectroscopy, where their unique properties provide significant advantages over traditional beam splitters.
