Ball Lenses |
Description: |
Ball lenses are commonly used for laser collimating and focusing, laser-to-fiber coupling, fiber-to-fiber coupling, and fiber-to-detector coupling. Larger spheres are easier to handle and ease the sensitivity of translational alignment. However, smaller spheres fit into smaller packages. Coupling efficiency is generally >90% due to the simplicity of these lenses. Specifications: Material: N-BK7 grade A optical glass Dimension Tolerance: +0.0, -0.03mm Surface quality: 60/40 Clear Aperture: >85% Surface Figure: λ/2 @633nm Centration: 3 arc minutes Note: Diameter: available from Φ1.0mm to Φ25mm All surfaces polished
