LBTEK plano-convex lenses are made from UV fused silica glass, which offers improved homogeneity and a lower thermal expansion coefficient than N-BK7 glass. They are primarily used in the UV and near-infrared regions. They have a positive focal length and are often used in imaging or beam collimation applications. LBTEK mounted lenses are mounted in standard lens tubes, which are engraved with the model number, type, diameter, and focal length for quick identification.

LBTEK lenses are often mounted on fixed lens mounts

LBTEK plano-convex lenses are made of UV-grade fused silica glass, offering better homogeneity and lower thermal expansion coefficient compared to N-BK7 glass, making them ideal for ultraviolet and near-infrared wavelength applications. LBTEK plano-convex lenses feature positive focal lengths and are commonly used in imaging or beam collimation applications. All LBTEK unmounted lenses can be installed in LBTEK standard lens tubes, fixed lens mounts, and various coaxial mounting plates, allowing customers to choose the optimal mounting solution for different application scenarios.
