LA4148-B UVFS Plano-Convex Lens; Dia:1 in; f=50 mm ARC 650-1050nm

The LA4148-B UVFS Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 1 inch (25.4 mm), is designed for use in the 650-1050nm wavelength range, making it suitable for a wide range of applications in the near-infrared spectrum.

The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light collection and focusing. The lens has a focal length of 50.2 mm, as indicated by its effective focal length (EFL), which is a key parameter in determining the lens's magnification and field of view.

The LA4148-B UVFS Plano-Convex Lens is made from UVFS material with a refractive index (RI) of 1.49, which is a common material for optical lenses due to its excellent transparency and low dispersion. The lens's front and back surfaces are coated with a broadband anti-reflection coating (ARC), specifically the "tho b bbar" coating, which reduces surface reflections and increases transmission, thereby enhancing the overall performance of the lens.

The lens has a center thickness of 5.8 mm and an edge thickness of 2 mm, providing structural rigidity while maintaining a low profile. The inner and outer radii are 0, indicating a symmetrical curvature. The lens's shape is spherical, which is the most common and versatile lens shape, suitable for a wide range of optical systems.
