LD Collimators & Diffractive Optics: Beam-Splitter
Diffractive beam splitters excel in providing precise control over the angles and intensities of split beams, making them ideal for high-precision applications such as laser systems, optical metrology, and advanced display technologies. Their compact and lightweight design, combined with wavelength specificity and high efficiency, ensures they perform exceptionally well in portable devices and systems where space and weight are critical. Additionally, their ability to generate complex beam patterns enhances their utility in spectroscopy and other fields requiring detailed spectral analysis.
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.
