The LA4917-UV is a UV fused silica plano-convex lens, meticulously crafted by Thorlabs. This lens boasts a diameter of 6 mm and a focal length of 15.1 mm, making it a versatile choice for various optical applications.
The lens's geometry is characterized by a thickness of 1.5 mm at the edge and 2.2 mm at the center, with an effective focal length (EFL) of 15 mm. The radius of curvature (R1) is 6.9 mm, and the back focal length (BFL) measures 13.5 mm. The inner and outer radii are both 0 mm, indicating a flat surface on the opposite side of the convex curve.
This lens is constructed from UV fused silica, a material with a high transmission range from 190 to 2000 nm, making it ideal for UV applications. The lens is coated with a UV ARC coating, specifically designed for the 245-400 nm range, further enhancing its performance in UV applications.
