LA4795-UV UV Fused Silica Plano-Convex Lens; Dia:75 mm; f=200.7 mm ARC 245-400nm
The LA4795-UV is a UV Fused Silica Plano-Convex Lens, meticulously crafted by Thorlabs. This lens boasts a diameter of 75 mm and a focal length of 200.7 mm, making it a versatile choice for various optical applications.
The lens's geometry is characterized by a thickness of 3 mm at the edge and 11 mm at the center, with an effective focal length (EFL) of 200 mm. The radius of curvature (R1) is 92 mm, and the back focal length (BFL) measures 192.5 mm. The lens's inner and outer radii are both 0, indicating a planar surface on one side and a curved surface on the other.
The lens is constructed from UV Fused Silica, a material with the Material ID "uvfs mal- 1965". This material is known for its excellent transparency in the ultraviolet region, making this lens particularly suitable for UV applications.
The LA4795-UV is coated with a UV ARC coating, specifically designed for the wavelength range of 245-400 nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the specified wavelength range.
