Description:
LD Collimators & Diffractive Optics: Beam-Splitter
A beam splitter in the context of diffractive optics is a device that utilizes diffractive elements to divide a beam of light into two or more separate beams. Unlike traditional beam splitters that use partial reflection and transmission through materials like glass, diffractive beam splitters rely on the principles of diffraction and interference to achieve the splitting.
