For spherical lenses, a given focal length can be obtained through different combinations of curvature radii on the front and rear surfaces. However, each surface combination results in varying degrees of spherical aberration. The best-form lenses optimize the curvature radius of each surface to minimize spherical aberration, making them suitable for infinite conjugate applications. LBTEK Best-Form Lenses are manufactured using N-BK7 glass that complies with RoHS standards. N-BK7 is the most commonly used material for high-quality optical components.\n\nLBTEK offers uncoated best-form lenses as well as lenses with three types of AR coatings: 400 nm–700 nm, 700 nm–1100 nm, and 1100 nm–1650 nm.

For spherical lenses, a given focal length can be obtained through different combinations of curvature radii on the front and rear surfaces. However, each surface combination results in varying degrees of spherical aberration. The best-form lenses optimize the curvature radius of each surface to minimize spherical aberration, making them suitable for infinite conjugate applications. LBTEK Best-Form Lenses are manufactured using N-BK7 glass that complies with RoHS standards. N-BK7 is the most commonly used material for high-quality optical components.\n\nLBTEK offers uncoated best-form lenses as well as lenses with three types of AR coatings: 400 nm–700 nm, 700 nm–1100 nm, and 1100 nm–1650 nm.
