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.
