Precision Light Control with Diffractive Optical Elements
Diffractive Optical Elements (DOEs) are advanced optical components that precisely control light using micro-structured surface patterns. Unlike conventional optics that rely on refraction, DOEs manipulate light through diffraction, enabling highly accurate beam shaping, splitting, and image generation.
These elements are widely used in industrial, scientific, and security applications where precise light control and compact optical design are essential.
