Uncoated Ø6.0 mm N-BK7 Plano-Convex Lenses

Features

• Material: N-BK7
• Wavelength Range: 350 nm - 2.0 μm (Uncoated)
• Focal Lengths Available from 4 to 2500 mm

These uncoated Plano-Convex Lenses are fabricated from RoHS-compliant N-BK7 glass. N-BK7 is typically chosen whenever the additional benefits of UV fused silica (i.e., good transmission further into the UV and a lower coefficient of thermal expansion) are not necessary. They have a positive focal length and near-best-form shape for infinite and finite conjugate applications.

Plano-convex lenses can focus a collimated beam or collimate light from a point source. To minimize the introduction of spherical aberration, a collimated light source should be incident on the curved surface of the lens when being focused and a point light source should be incident on the planar surface when being collimated.
