LA4904-UV UV Fused Silica Plano-Convex Lens; Dia:2 in; f=150.5 mm ARC 245-400nm

The LA4904-UV is a UV Fused Silica Plano-Convex Lens, sourced from the renowned optical components manufacturer, Thorlabs. This lens boasts a diameter of 2 inches (50.8 mm) and a focal length of 150.5 mm, making it suitable for a wide range of applications.

The lens is designed with a spherical shape, featuring a plano-convex base shape and a circular geometry. The edge thickness measures 3 mm, while the center thickness is 7.8 mm, providing a robust structure that can withstand typical handling and usage. The lens has an effective focal length (EFL) of 150 mm and a back focal length (BFL) of 144.6 mm, offering a decent balance between field of view and focus.

The LA4904-UV is crafted from UV Fused Silica, a high-quality material known for its excellent transparency in the ultraviolet region. This makes the lens ideal for applications that require UV transmission, such as UV curing, fluorescence microscopy, and various analytical instruments.

The lens is coated with a UV ARC coating, specifically designed for the 245-400 nm wavelength range. This coating enhances the lens's performance by reducing surface reflections and increasing transmission in the specified UV range.
