Product Description

• The optimal choice for high-power applications
• Best performance design for spherical single lenses
• Achieves diffraction-limited performance with small input beam diameters
• Operating wavelength: 1100 nm-1650 nm (with anti-reflection coating)

LBTEK Best Form Lenses are specifically designed to minimize spherical aberration in spherical lens systems. For spherical lenses, a given focal length can be achieved with different combinations of surface radii, but each configuration introduces varying levels of spherical error. Best form lenses optimize the radii of curvature on both surfaces to achieve the lowest spherical aberration, making them ideal for use at infinite conjugates. LBTEK Best Form Lenses are manufactured from RoHS-compliant N-BK7 glass, one of the most widely used materials for high-quality optical components. To meet diverse application needs, LBTEK offers both uncoated best form lenses and AR-coated versions optimized for 400–700 nm, 700–1100 nm, and 1100–1650 nm. All lenses undergo precision manufacturing and strict quality control, ensuring that LBTEK delivers high-performance optical components at competitive prices.

• Substrate Material: N-BK7
• Operating Wavelength: 1100 nm-1650 nm (AR Coating)
• Application: Imaging, Beam Collimation, Focusing

LBTEK's best form lenses are an ideal replacement for cemented lenses in high-power applications at infinite conjugates. Since best form lenses can optimize the spot size to the minimum, they theoretically achieve diffraction-limited performance. To obtain the best focusing effect, the surface with a smaller radius of curvature should face the collimated light source. All circular lenses from LBTEK can be mounted in LBTEK standard lens sleeves, fixed lens mounts, and various coaxial mounting plates. Customers can choose the optimal mounting method for different application scenarios.
