Optical Grade Spherical Convex Lenses for Industrial Magnifier and Measuring Tool

Material & Core Properties:
Crafted from premium optical-grade materials—typically BK7 (H-K9L) or crown glass—these lenses offer exceptional clarity and durability for industrial environments. Key properties include:

• High Optical Clarity & Low Distortion: Precision annealing and fine grinding ensure excellent homogeneity and minimal wavefront distortion, providing a true-to-life magnified image critical for measurement accuracy.

• Precision-Ground Spherical Surfaces: Surfaces are figured to exacting radii with high surface accuracy (λ/4 or better), ensuring consistent magnification power and focal length across all production units.

• Robust Coating Options: Available with broadband anti-reflective (AR) coatings to reduce glare and enhance light transmission, or with protective hard coatings to resist scratches and chemical exposure in harsh settings.

• Mechanical Durability: The lenses are designed to withstand vibration, minor impacts, and environmental contaminants commonly found in workshops and production floors.

Primary Function:
The positive, converging design of the spherical convex lens serves two core functions in industrial applications:

1. Angular Magnification: To enlarge small objects, surface details, or fine print, enabling visual inspection of defects, assembly alignment, or component identification.

2. Focal Point Precision: To provide a well-defined focal plane, which is essential for measurement tools that rely on precise optical alignment, such as toolmakers' microscopes or optical comparators.

Key Applications:

• Industrial Magnifiers: Integrated into handheld magnifying glasses, bench magnifiers, and inspection lamps for quality control (QC), electronics assembly (PCB inspection), and jewelry crafting.

• Precision Measuring Instruments: A core component in optical micrometers, profilometers, autocollimators, and linear measurement systems where accurate edge detection and feature sizing are critical.

• Machine Vision & Automated Inspection: Used as primary or auxiliary optics in automated imaging systems for part verification, dimension checking, and flaw detection.

• Tooling & Fabrication: Essential in alignment scopes, drilling jigs, and engraving machines to guide precise mechanical operations.
