Description:
LD Collimators & Diffractive Optics: Crosshair
A diffractive crosshair is an advanced optical element designed to create a crosshair pattern using the principles of diffraction. Unlike traditional optics that rely on refraction or reflection, diffractive optics utilize the wave nature of light to manipulate and shape it in unique ways. The core component of this system is a diffractive optical element (DOE), which features a microstructured surface capable of altering the phase of light that passes through it. These microstructures are meticulously engineered to produce specific light patterns, such as a crosshair consisting of two perpendicular lines intersecting at a central point, reminiscent of the reticles used in optical sights.
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.
