    High Transmission AR Coating Optical Achromatic Doublet Convex Lens for Collimator



    High Transmission AR Coating Optical Achromatic Doublet Convex Lens for Collimator


    1. Glass Material

      • Achromatic Doublet Design: Combines two optical glasses (e.g., crown glass N-BK7 and flint glass N-SF11) to eliminate chromatic aberration.

      • High-Quality Optics: Schott or equivalent glass with low impurity levels, ensuring minimal scatter and high transmission (400–700 nm range).

      • Anti-Reflective (AR) Coating‌: Reduces surface reflections, enhancing light transmission and reducing glare.
      • Achromatic Correction‌: Eliminates chromatic aberration, ensuring that images remain sharp and focused across a range of visible wavelengths.
      • Doublet Design‌: Combines two lenses with different refractive indices to further correct aberrations and improve image quality.
      • Convex Shape‌: Provides a wide field of view and good imaging performance.
    2. Primary Functions

      • Color Accuracy: Delivers sharp, true-color images by minimizing wavelength-dependent focal shifts.

      • High-Efficiency Focusing: Convex design concentrates light for precise beam collimation or magnification.

      • Reflection Control: AR coating eliminates ghosting in multi-lens systems (e.g., cameras, telescopes).

    3. Applications

      • Microscopy & Imaging: Critical in high-resolution microscopes, DSLR lenses, and telecentric systems.

      • Laser Systems: Collimators, beam expanders, and fiber-optic coupling in industrial/medical lasers.

      • Astronomy: Telescope objectives and eyepieces for clear celestial observation.

      • Machine Vision: Barcode scanners, metrology tools, and automated inspection systems.

      • Medical Devices: Endoscopes, OCT imaging, and ophthalmic diagnostics.

      • Defense & Aerospace: Targeting optics, rangefinders, and surveillance systems.

    4. Advantages Over Singlet Lenses

      • Superior Color Fidelity: Achromatic design reduces axial/lateral chromatic aberration.

      • Enhanced Resolution: AR coating improves contrast for fine-detail imaging.

      • Multi-Wavelength Performance: Effective across UV, visible, and near-IR ranges with custom coatings
