GE plano-convex lens

• Material: Ge
• Machinable diameter: Ø1-Ø500mm
• Focal length range: 4.5-1000mm
• Wavelength range: 2-16μm (uncoated), 7-12μm (IR2 broadband anti-reflection film)

       The Germanium 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.

Ge plano-convex lenses are based on germanium, which has a wide operating range (2-16 μm) and is impermeable in the visible spectrum, making them suitable for infrared laser applications. It is also inert to air, water, alkali metals and acids other than nitric acid, but its transmission properties are extremely sensitive to temperature, and the material becomes opaque at 100°C and completely impermeable at 200°C.

Dimension-Labs offers a wide range of formats of uncoated Ge plano-convex lenses (specific sizes and parameters can be filtered from the details below) and a contrast enhancement film (IR2 broadband anti-reflection film) to meet the variety of applications you need.

Precautions for use: Because germanium material will be harmful when it is stained with dust. To ensure your safety, please wear gloves when performing the relevant elements and clean your hands thoroughly after the operation is complete.
