*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 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.
Diffractive beam splitters offer several advantages. They provide precise control over the angles and intensities of the split beams, can be very thin and lightweight compared to traditional beam splitters, and can be designed to work efficiently with specific wavelengths of light. Applications of diffractive beam splitters include laser systems for splitting laser beams into multiple paths for parallel processing, optical metrology in interferometers and other measurement devices, display technology in projection systems and holographic displays, and spectroscopy for dispersing light into its constituent wavelengths.
A diffractive pattern generator leverages the principles of diffraction and interference using specially designed optical elements to create and project specific light patterns for a wide range of scientific, industrial, and commercial applications.
