Description:
LD Collimators & Diffractive Optics: Crosshair
A diffractive crosshair is a type of optical element designed to create a crosshair pattern using the principles of diffraction. Diffractive optics utilize the wave nature of light to manipulate and shape light in ways that are not possible with traditional refractive or reflective optics.
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.
