It is commonly used for beam collimation, increasing (or decreasing) the focal length, or enlarging (or reducing) images. To minimize spherical aberration, when the incident beam is collimated, it should be directed onto the concave surface of the plano-concave lens.\nN-BK7 is the most common lens material, widely used in visible and near-infrared applications. In addition to N-BK7 plano-concave lenses, LBTEK also offers N-SF11, UV fused silica, and calcium fluoride plano-concave lenses. Due to its lower Abbe number, N-SF11 is often used to produce lenses with shorter focal lengths. UV fused silica exhibits excellent transmittance in the ultraviolet range and a low coefficient of thermal expansion, while calcium fluoride boasts an extremely high damage threshold and chemical inertness.\nLBTEK provides uncoated plano-concave lenses as well as lenses with three types of anti-reflection coatings: 400 nm-700 nm, 700 nm-1100 nm, and 1100 nm-1650 nm. All our lenses undergo precision machining and strict quality control, ensuring that LBTEK delivers high-quality lens products to customers at reasonable prices.\u003c\/p\u003e\n\u003ch3\u003ePlano-Concave Lens, N-BK7, AR Coating: 1100 nm-1650 nm, Unmounted\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate Material: N-BK7\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 1100 nm-1650 nm (AR Coating)\u003c\/li\u003e\n\u003cli\u003eApplication: Imaging, Beam Expansion or Reduction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe LBTEK Plano-Concave Lens has a negative focal length and is commonly used in applications such as imaging or beam collimation. LBTEK plano-concave lenses are manufactured using N-BK7 glass that complies with RoHS standards. N-BK7 is the most commonly used material for high-quality optical components, primarily applied in visible and near-infrared fields. All circular lenses from LBTEK can be mounted in LBTEK standard lens tubes, fixed lens holders, and various coaxial mounting plates. Customers can choose the optimal mounting method based on different application scenarios.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47517952180378,"sku":"CC10610-C","price":47.41,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/2-1_E5_B9_B3_E5_87_B9_E9_80_8F_E9_95_9C_EF_BC_8CN-BK7_EF_BC_8C_E5_A2_9E_E9_80_8F_E8_86_9C_EF_BC_9A1100_20nm-1650_20nm_EF_BC_8C_E6_9C_AA_E5_AE_89_E8_A3_85-Fli5zxm_cAXi-slhFl5N4KUrfpSw_91d39ec5-2520-4274-b4f3-4c7779d9500d.jpg?v=1772672757","url":"https:\/\/waveqvanta.com\/products\/plano-concave-lens-n-bk7-ar-coating-1100-nm-1650-nm-cc10610-c","provider":"WaveQuanta","version":"1.0","type":"link"}
