Description:
LD Collimators & Diffractive Optics: Crosshair
A diffractive crosshair is an advanced optical element that uses microstructured surfaces to diffract light, creating a precise crosshair pattern. This technology is utilized in optical sights, metrology, alignment tasks, and display technologies, providing high precision and compactness compared to traditional optics. By manipulating the phase of light through diffraction and interference, diffractive optics crosshairs deliver exact patterns for various high-precision applications.
LD Collimators & Diffractive Optics: Pattern-Generator
A diffractive pattern generator is a device or system that uses the principles of diffractive optics to create specific light patterns. Diffractive optics involves the manipulation of light through structures with dimensions comparable to the wavelength of light, typically using interference and diffraction effects.
