Fast Axis Orientation of Liquid Crystal Molecules in Cubic Phase Distribution, λ/2 Retardance
Polarization-Dependent, Available for Airy Beam Generation
Output Airy Beam Exhibits Transverse Self-Accelerating, Self-Healing, and Non-Diffracting Properties
Operating Wavelength λ: 633 nm
Supports Flexible Customization of Specifications

LBTEK Airy Beam Converter (AB) is a two-dimensional, first-order Airy beam converter fabricated from Liquid Crystal Polymer (LCP) and N-BK7 window materials, featuring a sandwich structure of front and rear glass substrates with a central LCP functional layer, no housing, and a single 1.5 mm flat edge. In the LCP layer, the liquid crystal polymer molecules form a cubic phase distribution with a uniform λ/2 retardance across the entire element plane, making it a single-wavelength element. The Airy beam converter is a polarization-dependent element that can convert a Gaussian beam into an Airy beam exhibiting transverse self-acceleration, self-healing, and non-diffraction properties. Its applications in particle manipulation, material processing, microscopic imaging, and optical detection have been widely studied. LBTEK offers a standard Airy beam converter with an operating wavelength of 633 nm and supports flexible customization of specifications to meet diverse requirements in different applications.
