*Large-angle pattern that due to its symmetry properties is subject to geometrical distortion, if the DOE is used at laser wavelengths significantly different (Δλ > 50nm) from the design wavelength.
Beam shaping optics in terms of diffractive optics involve the use of precisely engineered microstructures to control and shape light beams for a variety of advanced applications, leveraging the principles of diffraction to achieve high precision and flexibility.
A beam splitter in the context of diffractive optics is a device that utilizes diffractive elements to divide a beam of light into two or more separate beams. Unlike traditional beam splitters that use partial reflection and transmission through materials like glass, diffractive beam splitters rely on the principles of diffraction and interference to achieve the splitting.
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.
