LD Collimators & Diffractive Optics: Beam-shaping-Optics
Beam shaping optics, in the context of diffractive optics, refer to optical components that manipulate the phase, amplitude, or polarization of a light beam to achieve a desired output beam profile. These optics leverage the principles of diffraction to control and shape light in precise ways, allowing for tailored intensity distributions and phase fronts.
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.
