Product DescriptionProduct DescriptionBi-convex lenses are a cornerstone in the world of optics, thanks to their distinctive product features that make them indispensable for a wide range of applications. Here's a closer look at the key product features that set bi-convex lenses apart:1. Converging Light Rays: The primary function of bi-convex lenses is to converge parallel light rays to a single focal point. This unique ability makes them essential for applications where light needs to be concentrated or focused, such as in cameras, projectors, and telescopes. When a parallel beam of light enters a bi-convex lens, the lens refracts the light rays, causing them to meet at a specific point on the optical axis, known as the focal point. 2. Positive Focal Length: Bi-convex lenses possess a positive focal length, indicating their ability to converge light. The focal length, typically specified in millimeters, is a key parameter of the lens. Different applications require bi-convex lenses with specific focal lengths. For instance, a lens with a shorter focal length will cause light to converge more rapidly, making it ideal for applications requiring high magnification. Conversely, a lens with a longer focal length is more suitable for applications where a more distant focal point is needed. 3. High-Quality Optics: Precision-manufactured to ensure accurate focusing and minimal optical aberrations, bi-convex lenses boast surfaces that are polished to a high degree of smoothness. This reduces the scattering and reflection of light, resulting in clear and sharp images. This feature makes bi-convex lenses particularly suitable for applications where high-resolution imaging is crucial, such as in scientific research, medical imaging, and high-end photography. In summary, bi-convex lenses are celebrated for their ability to converge light, their positive focal length, and their high-quality optics. These features make them a preferred choice for applications requiring precise light focusing and high-resolution imaging.SpecificationProduct:Optical Biconvex LensMaterials:Optical Grade Glass, N-BK7, UV fused silica, CaF2, ZnSe, ZnS, MgF2, Si, Sapphire, etc.Diameter:1.5mm-550mmDiameter Tolerance:±0.05 mm (precision ±0.01mm)Thickness:0.5mm-100mmThickness Tolerance:±0.05mm (precision ±0.01mm)Focal Length Tolerance:±1 %Surface Quality:20-10 scratch-dig (up to 10-5 available)Flatness:PV<1/4L@ 633nm (up to 1/10L); RMS<1/40LSurface Roughness:Rq<0.5nmCentration:<3 arcmin (1 arcmin precision)Center:ETV<0.008mmChamfer:<0.1mmClear Aperture:≥90 % of DiameterAOI:0-55degCoatings:single-layer MgF2, broadband VIS, VIS-NIR, NIR I/II, telecom, or high-energy laser V-coatings (266nm, 355nm, 532nm, 1064nm, etc.)Applications1. Imaging Systems:Cameras: Bi-convex lenses focus light onto the image sensor or film, determining image sharpness, clarity, and magnification. They are essential for various photography styles—short focal lengths for wide-angle shots (e.g., landscapes) and long focal lengths for telephoto shots (e.g., wildlife or sports). Projectors: These lenses magnify and project light onto screens, directly influencing brightness, contrast, and resolution. High-quality bi-convex lenses ensure sharp, bright projections. 2. Astronomical Tools:Telescopes: Bi-convex lenses gather and focus light from distant celestial objects. Their focal length and aperture dictate magnification and light-gathering power, enabling detailed observations of stars, planets, and galaxies. 3. Medical Devices:Endoscopes: Used in minimally invasive surgeries, bi-convex lenses help focus light to provide clear internal body images. Ophthalmology: Instruments like phoropters and retinoscopes use these lenses to correct and assess vision. 4. Scientific Instruments:Microscopes: Bi-convex lenses are critical in objective and eyepiece lenses, magnifying tiny specimens for detailed analysis. Spectrometers: They focus light into narrow beams for spectral analysis in chemistry and physics. 5. Consumer Electronics:Laser Systems: In CD/DVD players and laser pointers, bi-convex lenses focus laser beams for accurate data reading or beam collimation. 6. Industrial Applications:Laser Cutting/Engraving: These lenses concentrate laser beams for precise material processing. Optical Sensors: Used in quality control systems to focus light for accurate measurements. 7. Educational Tools:Physics Demonstrations: Basic optics experiments often use bi-convex lenses to illustrate principles like refraction, focal length, and image formation.InspectionsProduction LineCompany ProfileFactory AdvantagesAs a total solution provider on Optics, we can match your different demands as below optical components:---Automated, High-Speed and Low-Speed Precision Polished Optics---Precision Optical Domes for Demanding Applications---Optical Lens, Spherical Lenses, Aspherical Lenses---Optical Mirrors---Optical Windows---Optical Prisms---Optical Filters---Camera AssemblyCertifications
