It is commonly used to generate beams with Bessel intensity profiles or ring-shaped beams. When converting a collimated beam into a ring-shaped beam, the planar side of the axicon should face the collimated light source.\n\nLBTEK manufactures axicons using UV fused silica, which is suitable for a wide range of ultraviolet, visible, and near-infrared applications. With its low refractive index, low coefficient of thermal expansion, and high hardness, it is ideal for harsh working environments. LBTEK offers uncoated axicons with four different apex angles (α): 0.5°, 1°, 2°, and 5°.\n\nAll our axicons are precision-engineered and undergo strict quality control, ensuring that LBTEK provides high-quality lens products at competitive prices. Custom axicon solutions are available.
