It is commonly used to generate beams with Bessel-like intensity distributions or annular (ring-shaped) beams. When converting a collimated beam into an annular beam, the flat surface 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 applications across ultraviolet, visible, and near-infrared spectra. This material offers a low refractive index, low thermal expansion coefficient, high hardness, and excellent performance in harsh working environments.\n\nLBTEK offers axicons with two distinct apex angles (α): 2° and 5°. All our axicons are precision-engineered and undergo strict quality control to ensure that customers receive high-quality optical products at reasonable prices. Custom axicon solutions are also available.

We offer four different apex angles (α) of 2° and 5° to choose from. Each lens features an arrow marked on the edge, pointing toward the conical surface. Additionally, the lenses are coated with an anti-reflection coating for 400 nm-700 nm wavelength range to minimize surface reflection and enhance transmittance.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47518184833178,"sku":"CL20620-A","price":756.98,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_E9_94_A5_E9_80_8F_E9_95_9C_EF_BC_8C_E5_A2_9E_E9_80_8F_E8_86_9C_EF_BC_9A400-nm-700-nm-Fh52AjGqniYnrYKuRiiL8kU_uvnn_9f3f73a3-3516-487c-a008-bb16cd136afd.jpg?v=1772677906","url":"https:\/\/waveqvanta.com\/products\/axicons-anti-reflection-coating-400-nm-700-nm-cl20620-a","provider":"WaveQuanta","version":"1.0","type":"link"}
