*Large-angle pattern that due to its symmetry properties is subject to geometrical distortion, if the DOE is used at laser wavelengths significantly different (Δλ > 50nm) from the design wavelength.
Beam shaping optics excel in applications that demand precise control of light for improved performance, efficiency, and accuracy. Their versatility and precision make them indispensable in diverse fields ranging from industrial processing and medical surgery to optical communication and scientific research.
A diffractive beam splitter uses the principles of diffraction and interference to split a light beam into multiple beams, offering high precision and control in various optical applications.
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.
