Features

Diffraction Phase Transmission Grating Key Features:



  • Our bit-phase diffraction grating is a planar laminar structure.

  • All grating directions are parallel to the edges, suitable for specific installation and incidence angle control scenarios

  • The material is fused silica, which has high transmittance, high stability and resistance to laser damage.

  • The center wavelength is designed to match commonly used laser wavelengths such as 650nm, 808nm and 980nm.

  • Multiple line density and period parameters are available to accommodate different resolutions and diffraction angles.

Applications

Diffraction Phase Transmission Grating Applications



  • High Power Laser
    In high power laser processing, cutting and welding applications, phase diffraction gratings can be used for beam shaping, or designed as a single or multi-stage DOE system to multipoint beam splitting and focusing lasers.

  • Consumer Electronics
    In applications such as face recognition, AR/VR and other 3D perception and imaging applications, phase diffraction gratings are one of the core devices, which can realize complex light field design, projection of structured light in modules, and spot irradiation.

  • Scientific Research
    Wavefront modulation and interference experiments are often designed in experiments for scientific research, and phase diffraction gratings can realize complex optical requirements, such as Fourier transforms and Bessel beams. Diffraction phase gratings can be used as wavefront controllers or diffractive elements for laser modulation, optical simulation, etc.
