UV Fused Silica Biconvex Lenses
Positive Focal Lengths: Biconvex lenses have positive focal lengths, allowing them to converge collimated light to a point.
Versatile Applications: They are primarily used for laser beam modulation, light focus, and imaging, making them suitable for a wide range of optical systems.Optimal Conjugate Ratio: Biconvex lenses are recommended when the absolute finite conjugate ratio is equivalent to or near 1:1, providing optimal performance in these conditions.
High-Quality Material: Made from UV Fused Silica (JGS1), these lenses offer exceptional transmittance to UV wavelengths, while also being widely transparent to visible and NIR wavelengths.
Excellent Thermal Properties: UV Fused Silica lenses exhibit high-temperature endurance and low thermal expansion, ensuring stable performance in harsh working conditions.
Additional Benefits: These lenses are known for their few bubbles/striae, high homogeneities, chemical inertness, mechanical hardness, and birefringent properties.
Applications: Optical Systems, Scientific Research, Medical Equipment, Aerospace and Defense, etc.

Kingwin Optics’ Stocked UV-Fused Silica Biconvex Lenses are high-quality optical lenses with two identical spherical sides and the same curvature radii. These lenses are primarily used for laser beam modulation, light focus, and imaging. With positive focal lengths, they converge collimated light to a point. Biconvex lenses are recommended when the absolute finite conjugate ratio is equivalent to or near 1:1, making them the best option for conjugate ratios between 1:5 and 5:1.
Our UV-Fused Silica lenses are made from an optical glass material with exceptional transmittance to UV wavelengths, while also being widely transparent to visible and NIR wavelengths (transmission range 200-2200 nm). UV Grade Fused Silica is one of the best ultraviolet-transmitting media, with prominent thermal properties including high-temperature endurance and low thermal expansion.
Within our stock list, a wide range of focal lengths (10-1000mm) and diameters (5.0-50.8mm) are available. However, stocked N-BK7 Biconvex Lenses and custom biconvex lenses made from BaF2, CaF2, MgF2, Ge, ZnSe, Sapphire, and other optical materials are also procurable upon request. The UV Fused Silica double convex lenses in our stock list are uncoated, but designed coatings can be tailored according to customers’ requirements to further enhance transmission. In addition to conventional BBAR coatings, Kingwin Optics also provides V coatings consisting of multiple high-performance layers for minimum reflectance over a contracted spectral range and low-cost MgF2 coatings.
