Bevel/Edge: Chamfer Width 0.5-2.0 mm, Edge Radius 0.1-0.5 mm

Q: Why is bevel angle critical for focusing lenses?

The bevel angle determines how light interacts with the lens edge. Proper angles minimize back reflections, reduce edge diffraction that causes beam distortion, and ensure compatibility with lens mounting systems.

Q: Can beveled edges be added to existing lenses?

Yes, through precision grinding and polishing processes, but this requires specialized optical manufacturing equipment and may affect lens coatings. Original manufacturing with integrated bevels is preferred for optimal performance.

Q: How does bevel quality affect laser system performance?

Poor bevel quality causes stray light reflections that reduce beam energy, create hot spots, and potentially damage optical components. Precision bevels ensure maximum energy delivery and system reliability.

Component Specifications

Definition

A precisely machined beveled edge on a focusing lens that serves critical optical functions including beam alignment, reduction of edge diffraction effects, and prevention of internal reflections. This component ensures optimal laser energy delivery by controlling the angle at which light enters and exits the lens material.

Working Principle

The beveled edge functions through geometric optics principles, creating a controlled angle transition between the lens surface and its mounting interface. This angled surface redirects stray light away from the optical path, minimizes edge scattering, and facilitates proper seating in lens holders. The specific bevel angle is calculated based on the lens material's refractive index and the intended laser wavelength.

Materials

Typically matches the lens substrate material: fused silica (SiO₂), zinc selenide (ZnSe), germanium (Ge), or sapphire (Al₂O₃). Material purity >99.9% with optical-grade surface finish. Coating materials may include anti-reflective coatings (MgF₂, SiO₂) applied to the bevel surface.
