High Precision Bi-convex Magnifier Lens for Machine Vision Camera & Barcode Scanner Optical System

1. Core Material & Optical Design:

• Material: Manufactured from premium optical glass (e.g., N-BK7, H-K9L) with optional anti-reflective coatings.

• Design: Features a precise Bi-convex (DCX) shape, where both lens surfaces curve outward symmetrically, providing a positive focal length and magnification.

2. Defining Physical & Optical Properties:

• High Precision & Low Aberration: Precision-ground and polished to minimize spherical aberration, distortion, and chromatic aberration, ensuring accurate image reproduction.

• Positive Magnification: Effectively converges light to magnify objects and project real, inverted images onto a sensor.

• High Resolution & Contrast: Optimized for sharp focus and high contrast, critical for capturing fine details and reading high-density codes.

• Durable Construction: Often housed in robust metal barrels for precise alignment, stability, and protection in industrial environments.

3. Primary Functions in an Optical System:

• Image Formation & Magnification: Serves as the primary objective lens to collect light, form a clear image, and provide the initial magnification for the camera sensor.

• Light Collection: Its convex surfaces gather a wide cone of light, improving system brightness and efficiency, especially in low-light conditions.

• Field-of-View (FOV) Control: Determines the angular field of view of the camera system, defining the area inspected or scanned.

4. Target Applications & Industries:

• Machine Vision & Factory Automation: Used in inspection systems, robotic guidance, metrology, and quality control cameras.

• Barcode & QR Code Scanners: Acts as the core imaging lens in fixed-mount and handheld scanners for logistics, retail, and inventory management.

• OCR (Optical Character Recognition) Systems: For reading text and serial numbers in manufacturing and documentation.

• Medical & Scientific Imaging: In diagnostic equipment and laboratory instruments requiring precise magnification.
