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. ZnSe plano-convex lenses from LBTEK are coated with 7–12 μm AR coating on both surface to reduce the reflectivity of the lens. ZnSe is selected for its high transmittance across mid-to-far infrared spectra, with a refractive index of approximately 2.89 in the 0.5–15 μm range. Its low absorption at 10.6 μm makes it the preferred material for high-power CO₂ laser optics, while its broad transmission band also enables widespread use in various optical systems. Note that ZnSe is toxic, wearing gloves when handling and wash hands after use. All lenses undergo precision machining and strict quality control, ensuring LBTEK delivers high-quality optical products at competitive prices.\u003c\/p\u003e\n\u003ch3\u003ePlano-Convex Lens, ZnSe, AR Coating: 7 μm-12 μm\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Material: ZnSe;\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 7 μm-12 μm;\u003c\/li\u003e\n\u003cli\u003eApplication: Beam Expander, Imaging, Beam Reducer;\u003c\/li\u003e\n\u003cli\u003ePre-mounted mechanical housing;\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47517952540826,"sku":"MCX90621-E3","price":405.36,"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_B8_E9_80_8F_E9_95_9C_EF_BC_8CZnSe_EF_BC_8C_E5_A2_9E_E9_80_8F_E8_86_9C_EF_BC_9A7_20_CE_BCm-12_20_CE_BCm-Fjawu4RsAruGidvPBwlxWBsmuCB1.jpg?v=1772672779"},{"product_id":"plano-convex-lens-znse-ar-coating-7-μm-12-μm-mcx90617-e3","title":"Plano-Convex Lens, ZnSe, AR Coating: 7 μm-12 μm MCX90617-E3","description":"\u003ch2\u003ePlano-Convex Lens, ZnSe, AR Coating: 7 μm-12 μm — Model MCX90617-E3\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003eOperating wavelength 7 μm-12 μm, focal length 200.0 mm, Ø25.4 mm, substrate ZnSe.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Material: ZnSe;\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 7 μm-12 μm(AR Coating);\u003c\/li\u003e\n\u003cli\u003eApplication: Imaging, beam expander or reducer, 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.

ZnSe is selected for its high transmittance across mid-to-far infrared spectra, with a refractive index of approximately 2.89 in the 0.5–15 μm range. Its low absorption at 10.6 μm makes it the preferred material for high-power CO₂ laser optics, while its broad transmission band also enables widespread use in various optical systems. Note that ZnSe is toxic, wearing gloves when handling and wash hands after use. All lenses undergo precision machining and strict quality control, ensuring LBTEK delivers high-quality optical products at competitive prices.\u003c\/p\u003e\n\u003ch3\u003ePlano-Convex Lens, ZnSe, AR Coating: 7 μm-12 μm, Unmounted\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Material: ZnSe;\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 7 μm-12 μm;\u003c\/li\u003e\n\u003cli\u003eApplication: Beam Expander, Imaging, Beam Reducer;\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAddress：Building A6, Huanchuang Enterprise Plaza, Yuelu Idstrict, Changsha\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47517954277530,"sku":"CX90610-E3","price":401.45,"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_B8_E9_80_8F_E9_95_9C_EF_BC_8CZnSe_EF_BC_8C_E5_A2_9E_E9_80_8F_E8_86_9C_EF_BC_9A7_20_CE_BCm-12_20_CE_BCm_EF_BC_8C_E6_9C_AA_E5_AE_89_E8_A3_85-FgyrNTUMNRqkpK45WFxQehdrB_a5e244dd-87c4-49e3-b2f0-bbff0d8e5d9b.jpg?v=1772672843"},{"product_id":"plano-convex-lens-znse-ar-coating-7-μm-12-μm-cx90606-e3","title":"Plano-Convex Lens, ZnSe, AR Coating: 7 μm-12 μm, Unmounted CX90606-E3","description":"\u003ch2\u003ePlano-Convex Lens, ZnSe, AR Coating: 7 μm-12 μm, Unmounted — Model CX90606-E3\u003c\/h2\u003e\n\u003cp\u003e\u003cem\u003eOperating wavelength 7 μm-12 μm, focal length 25.4 mm, Ø25.4 mm, substrate ZnSe.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eProduct Description\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOptical Material: ZnSe;\u003c\/li\u003e\n\u003cli\u003eOperating Wavelength: 7 μm-12 μm(AR Coating);\u003c\/li\u003e\n\u003cli\u003eApplication: Imaging, beam expander or reducer, 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. 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. ZnSe plano-convex lenses from LBTEK are coated with 7–12 μm AR coating on both surface to reduce the reflectivity of the lens. ZnSe is selected for its high transmittance across mid-to-far infrared spectra, with a refractive index of approximately 2.89 in the 0.5–15 μm range.
