Product DescriptionProduct DescriptionAxicons are fascinating optical elements! Their ability to create non-diffracting Bessel beams and annular intensity profiles opens up unique applications that traditional spherical lenses simply cannot achieve. Let me search for more detailed information about their design principles and applications.SpecificationProduct:Optical Axicon Conical LensMaterials:Optical Grade Glass, N-BK7, UV fused silica, CaF2, ZnSe, ZnS, Ge, Si, Sapphire, etc.Diameter:1.5mm-550mmDiameter Tolerance:±0.05 mm (precision ±0.01mm)Thickness:0.5mm-100mmThickness Tolerance:±0.05mm (precision ±0.01mm)Focal Length Tolerance:±1 %Surface Quality:20-10 scratch-dig (up to 10-5 available)Flatness:PV<1/4L@ 633nm (up to 1/10L); RMS<1/40LSurface Roughness:Rq<0.5nmCentration:<3 arcmin (1 arcmin precision)Center:ETV<0.008mmChamfer:<0.1mmClear Aperture:≥90 % of DiameterAOI:0-55degCoatings:single-layer MgF2, broadband VIS, VIS-NIR, NIR I/II, telecom, or high-energy laser V-coatings (266nm, 355nm, 532nm, 1064nm, etc.)Key FeaturesOptical Axicon Conical LensDesign and Operation:Axicons feature one conical surface and one flat (plano) surface, with precise apex angles typically ranging from 0.5° to 25° depending on application The conical angle creates constant ray deflection, producing a line focus along the optical axis rather than a point focus Unlike spherical lenses, the surface inclination angle remains constant across the element Beam Transformation Properties:Convert Gaussian laser beams into Bessel beams with the intensity profile, where is the zeroth-order Bessel function Create non-diffracting beams that maintain their waist size over extended propagation distances Generate annular (ring-shaped) intensity profiles with multiple concentric rings around a central coreNon-Diffracting Distance: The maximum non-diffracting range is given by: where is the input beam radius, n is the refractive index, and α is the axicon angle.ApplicationsOptical Axicon Conical LensLaser Processing:Enable high-aspect-ratio microstructuring with femtosecond lasers Create predictable filamentation for deep penetration processing Achieve single-shot processing of transparent materials Optical Trapping:Bessel beams' self-healing property allows trapping multiple particles across different planes Maintain trapping efficiency over several millimeters Enable stable nanoparticle levitation for precision measurements Emerging Applications:Dark matter detection using levitated nanoparticles in Bessel-Gaussian beams Light-sheet microscopy for nanoscale imaging Free-space optical communication with improved resilience to atmospheric disturbances 3D sensing and LiDAR applications The unique properties of axicons make them invaluable for applications requiring extended depth of field, self-healing beam characteristics, and precise energy deposition along extended volumes.InspectionsProduction LineCompany HistoryFAQQ: What are your main products?A: Optical Components: Aspherical Lenses, Spherical Lenses, Cylindrial Lenses, Lens Assemblies, Optical Windows, Optical Mirrors, Optical Prisms, Optical Filters, and Other Special Shaped Optics......
