It utilizes diffraction principles with high efficiency and uniformity, applicable for objective lenses.\u003c\/p\u003e\n\u003cp\u003eMade of Liquid Crystal Polymer\/N-BK7 window material with a sandwich-style flat plate structure. The fast-axis orientation of liquid crystal molecules varies periodically along the radius, featuring λ\/2 retardation.\u003c\/p\u003e\n\u003cp\u003eThe multi-focal DOE focuses incident light into a fixed number of equally spaced, uniformly distributed focal points along the axial direction through diffraction-based phase modulation. Primarily used for laser deep cutting of transparent materials like glass and sapphire.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLiquid Crystal Polymer\/N-BK7 window material, sandwich flat plate structure\u003c\/li\u003e\n\u003cli\u003eGenerates multiple equally spaced focal points with uniform energy\u003c\/li\u003e\n\u003cli\u003eHigh diffraction efficiency and focal energy uniformity \u0026gt;95%\u003c\/li\u003e\n\u003cli\u003eApplicable with standard objective lenses\u003c\/li\u003e\n\u003cli\u003eFlexible customization available (wavelengths 400-1700 nm)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMulti-Focal DOE Series\u003c\/h3\u003e\n\u003cp\u003eOperating wavelength 1064 nm.
