Please see the Graphs tab for coating details. ![]() Links to each of these pages can be found in the table to the right. It is typically chosen whenever the additional benefits of UV fused silica (i.e., good transmission further into the UV and a lower coefficient of thermal expansion) are not necessary.Īlthough this page features our uncoated bi-convex lenses, these lenses are also available with one of three antireflection coatings (-A, -B, or -C) deposited on both sides to reduce the amount of light reflected from each surface. N-BK7 is probably the most common optical glass used for high-quality optical components. These lenses are designed to have a focal length of f= (R1*R2)/((n-1)*(R2-R1)). This type of lens is best suited for use in situations where the object and image are on opposite sides of the lens and the ratio of the image and object distances (conjugate ratio) is between 0.2 and 5. Thorlabs' uncoated N-BK7 Bi-Convex Lenses are popular for many finite imaging applications. Offers Excellent Transmittance Throughout the Visible and Near Infrared.Well Suited for Many Finite Imaging Applications.Focal Lengths Available from 10.0 mm to 1.0 m.Wavelength Range: 350 - 2000 nm (Uncoated).Please contact our Tech Support for a quote.
