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.
