LBTEK plano-convex lenses are made of UV fused silica, which provides better homogeneity and a lower thermal expansion coefficient compared to N-BK7 glass, making them especially suitable for use in the ultraviolet and near-infrared spectral ranges. With a positive focal length, LBTEK plano-convex lenses are commonly applied in imaging and beam collimation. LBTEK offers both unmounted and mounted plano-convex lenses for the 400–700 nm wavelength range, with available diameters of 12.7 mm, 25.4 mm, and 50.8 mm. The mounted versions come pre-installed in standard lens tubes, with the product model, type, diameter, and focal length engraved on the tube surface for quick and convenient identification.
