概述
- Material: Si (silicon)
- Machinable diameter: Ø1-Ø500mm
- Focal length range: 4.5-1000mm
- Wavelength range: 1.2-8μm (uncoated), 2-5μm (IR1 broadband anti-reflection film)
Silicon Plano Convex Lenses have a positive focal length and are suitable for applications such as imaging or beam collimation. To minimize spherical aberration, when used for collimating beam focusing, the beam should be incident on the lens surface; When used for point light collimation, it should be incident on the plane.
Silicon plano-convex lenses are based on silicon, and the transmission band of silicon is 1.2nm-8.0μm, which has high thermal conductivity and low density, and is used in the near-infrared, mid-infrared, and infrared fields.
Dimension-Labs offers a wide range of uncoated Si plano-convex lenses (specific sizes and parameters can be filtered from the details below) and a contrast enhancement film (IR1 broadband anti-reflection film) to meet the needs of a wide range of applications.
