LD Collimators & Diffractive Optics: Beam-Splitter
Diffractive beam splitters offer several advantages. They provide precise control over the angles and intensities of the split beams, can be very thin and lightweight compared to traditional beam splitters, and can be designed to work efficiently with specific wavelengths of light. Applications of diffractive beam splitters include laser systems for splitting laser beams into multiple paths for parallel processing, optical metrology in interferometers and other measurement devices, display technology in projection systems and holographic displays, and spectroscopy for dispersing light into its constituent wavelengths.
LD Collimators & Diffractive Optics: Pattern-Generator
A diffractive pattern generator leverages the principles of diffraction and interference using specially designed optical elements to create and project specific light patterns for a wide range of scientific, industrial, and commercial applications.
