Anti-Reflection Coated Optical Glass Convex Lens for Professional Photography

Anti-Reflection Coated Optical Glass Convex Lens for Professional Photography

Material & Core Properties:
Crafted from premium optical glass, typically fine-annealed B270 or equivalent high-transmission crown glass, this lens provides exceptional clarity and color fidelity.

• Anti-Reflection Coating: Multi-layer broadband AR coatings are applied to all air-glass surfaces. This technology dramatically reduces surface reflections (often to <0.5% per surface), minimizing lens flare and ghosting caused by stray light.

• High Light Transmission: The AR coating ensures over 99.5% light transmission across the visible spectrum (400-700nm), maximizing the efficiency of your lighting setup and preserving shadow detail.

• Precision Optical Figure: The convex spherical surface is accurately ground and polished to a high degree of surface accuracy (often λ/4 or better) to ensure uniform focusing without introducing unwanted optical aberrations.

• Scratch-Resistant Surface: The hard, durable coating protects the optical glass from minor abrasions, ensuring longevity on busy sets.

Primary Function:
This positive meniscus or biconvex lens is engineered to converge light rays. In professional photography, its core functions are:

• Light Concentration & Control: To gather and focus light from a source, increasing its intensity and directionality for efficient illumination over a controlled area.

• Image Quality Preservation: The AR coating is critical for maintaining high contrast and saturation by eliminating internal reflections that cause haze and reduce image pop, especially in backlit or high-contrast scenes.

• Optical System Integration: Serves as a key element within custom lens arrays, projection systems, and specialized optical attachments for creating specific photographic effects.

Key Applications:

• Studio & Portrait Lighting: Integrated into softboxes, beauty dishes, and spotlight modifiers to shape and focus strobe or continuous light with precision.

• Macro & Product Photography: Used in custom rigs for precise light focusing on small subjects, highlighting texture and detail without flare.

• Cine & Video Production: Essential for building lens systems for projectors, anamorphic attachments, or custom bokeh modification tools.

• High-End Optical Attachments: A core component in diopters, magnifiers, and custom filters designed to modify the optical path of primary camera lenses.
