It is commonly used for beam collimation, increasing (or decreasing) 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. N-SF11 has a lower Abbe number, making it suitable for 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 at reasonable prices.\u003c\/p\u003e\n\u003ch3\u003ePlano-Concave Lens, N-BK7, AR Coating: 400 nm-700 nm\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate Material: N-BK7\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 400 nm-700 nm (AR Coating)\u003c\/li\u003e\n\u003cli\u003eApplication: Imaging, Beam Expansion or Reduction\u003c\/li\u003e\n\u003cli\u003ePre-installed Mechanical Housing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eLBTEK Plano-Concave Lens have a negative focal length and are 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 come pre-installed with standard lens tubes or lens mounting adapters. These mechanical components are engraved with product model, type, diameter, and focal length for easy identification of lens parameters by users.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47517945233562,"sku":"MCC10612-A","price":55.78,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_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_9A400_20nm-700_20nm-FoEHO156_tA_39ShT5tupiEBRoII_ab1135c5-6bff-44cd-a4e9-512531b130e9.jpg?v=1772672483","url":"https:\/\/waveqvanta.com\/products\/plano-concave-lens-n-bk7-ar-coating-400-nm-700-nm-mcc10612-a","provider":"WaveQuanta","version":"1.0","type":"link"}
