To minimize spherical aberration, when a plano-convex lens is used for focusing a collimated beam, the beam should be incident on the curved surface; when collimating a point source, the beam should be incident on the flat surface. LBTEK manufactures these lenses using N-BK7, the most common optical material for visible light and near-infrared applications. The 780V coating offers lower reflectivity at the operating wavelength and higher damage thresholds, making it ideal for diode lasers and applications where light passes through complex optical systems. All lenses undergo precision machining and strict quality control, ensuring LBTEK delivers high-quality optical products at competitive prices.\u003c\/p\u003e\n\u003ch3\u003eNegative Meniscus Lens, N-BK7, Uncoated: 350 nm-2.0 μm\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSubstrate Material: N-BK7;\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 350 nm-2.0 μm (uncoated);\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47518088331418,"sku":"MMP10615","price":44.26,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_E8_B4_9F_E5_BC_AF_E6_9C_88_E9_80_8F_E9_95_9C_EF_BC_8CN-BK7_EF_BC_8C_E6_9C_AA_E9_95_80_E8_86_9C_EF_BC_9A350_20nm-2.0_20_CE_BCm-FlE0YNXy1t6s-2CTT55-5XvS6NPM.jpg?v=1772677132"},{"product_id":"negative-meniscus-lens-n-bk7-uncoated-350-nm-2-0-μm-mp10615","title":"Negative Meniscus Lens, N-BK7, Uncoated: 350 nm-2.0 μm, Unmounted MP10615","description":"\u003ch2\u003eNegative Meniscus Lens, N-BK7, Uncoated: 350 nm-2.0 μm, Unmounted — Model MP10615\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003eOperating wavelength 350 nm-2.0 μm, focal length -150.0 mm, Ø25.4 mm, substrate N-BK7.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Material: N-BK7;\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 350 nm-2.0 μm (uncoated)\u003c\/li\u003e\n\u003cli\u003eApplication: imaging, beam expander,convergence;\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe plano-convex lenses from LBTEK feature one convex surface and one flat surface, providing positive focal lengths typically used for beam reduction, focal length shortening, or imaging magnification applications.
