High Transmission AR Coating Optical Achromatic Doublet Convex Lens for Collimator
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).
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).
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.
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
