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
Diffractive pattern generators have a wide range of applications. In laser systems, they are used for beam shaping, allowing the laser beam to form desired shapes such as lines, circles, or complex patterns, which are essential in material processing, medical surgery, and laser printing. They play a crucial role in holography, creating holograms for data storage, security features on credit cards and passports, and 3D imaging. In optical testing and metrology, these generators produce specific patterns for testing optical components, measuring surface topography, and aligning optical systems. They are also used in displays and projection systems, including projectors and augmented reality devices, to create high-resolution and complex images. Additionally, they enhance the performance of optical communication systems by precisely controlling light propagation.
