LA4158-UV UV Fused Silica Plano-Convex Lens; Dia:1 in; f=250.9 mm ARC 245-400nm
This is the LA4158-UV UV Fused Silica Plano-Convex Lens, a high-quality optical component sourced from Thorlabs. The lens is designed with a plano-convex base shape, featuring a circular geometry. It has a diameter of 1 inch (25.4 mm) and a thickness of 2 mm at the edge, which gradually increases to 2.7 mm at the center.
The lens boasts an effective focal length (EFL) of 250 mm, making it suitable for a wide range of optical applications. The front and back surfaces of the lens are coated with a UV UV ARC coating, specifically designed for the 245-400nm wavelength range. This coating enhances the lens's performance by reducing surface reflections and improving transmission within the specified wavelength range.
The LA4158-UV is a spherical lens, meaning it has a curved surface that refracts light evenly in all directions. This property is crucial in maintaining the integrity of the optical path and ensuring the desired image quality.
