    Professional Optical Plano Convex Lens - High-Quality Large Magnifying Glass



    Professional Optical Plano Convex Lens - High-Quality Large Magnifying Glass


    1. Material & Construction

    • Optical-Grade Glass: Precision-crafted BK7 borosilicate glass (Schott/N-BK7 equivalent) with low dispersion properties.

    • Surface Quality: λ/4 surface accuracy and 60-40 scratch-dig specification for aberration-free imaging.

    • Coating: Optional broadband anti-reflective (BBAR) coating (>99.5% peak transmission, 400-700nm).


    2. Critical Optical Properties

    • High Magnification: Focal lengths from 50mm to 1000mm with 2X-10X magnification capabilities.

    • Exceptional Clarity: >99% light transmission (coated) with near-zero wavefront distortion.

    • Chromatic Control: Abbe number 64.2 minimizes color fringing at edges.

    • Thermal Stability: CTE 7.1×10⁻⁶/°C prevents deformation in variable environments.

    • Surface Precision: < 1/4 wave RMS @ 632.8nm for distortion-free imaging.


    3. Core Functions

    • Light Convergence: Positive focal length converges parallel light rays to a precise focal point.

    • Image Magnification: Enables high-resolution inspection of fine details (0.01mm resolution at 10X).

    • Beam Collimation: Converts point light sources into directional parallel beams.

    • Aberration Correction: Spherical design reduces edge distortion vs. biconvex alternatives.


    4. Professional Applications

    • Laboratory Equipment: Condenser lenses in microscopes, collimators, and optical test benches.

    • Industrial Inspection: PCB verification, jewelry appraisal, and forensic analysis magnifiers.

    • Photographic Systems: Projector lens assemblies and large-format camera optics.

    • Scientific Instruments: Telescope corrector plates, laser focusing optics, and spectrometer components.

    • Medical Devices: Dermatology loupes and surgical microscope attachments.
