LA4579-B UVFS Plano-Convex Lens; Dia:1 in; f=300 mm ARC 650-1050nm
The LA4579-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, is designed for use in the wavelength range of 650-1050nm, making it suitable for a wide range of applications in the near-infrared spectrum.
The lens is spherical in shape, with a plano-convex geometry. The base shape is circular, and the lens has a thickness of 2mm at the edge and 2.6mm at the center. The effective focal length (EFL) of this lens is 301.1mm, and the back focal length (BFL) is 299.3mm. The inner and outer radii are 0, indicating a uniform curvature.
The LA4579-B lens is made from UVFS, a material with the material ID "uvfs mal- 1965". This material is known for its excellent optical properties in the near-infrared range. The lens is coated with a broadband anti-reflection coating (BARC) on both the front and back surfaces, which enhances its transmission characteristics and reduces unwanted reflections.
