LB4545-A UV Fused Silica Bi-Convex Lens; Dia:1 in; f=300.0 mm ARC 350-700nm
The LB4545-A is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens is part of the UV Fused Silica family, characterized by its exceptional transmittance in the ultraviolet (UV) region, making it ideal for applications that require UV light manipulation.
The lens boasts a diameter of 1 inch (25.4 mm) and a focal length of 300.0 mm, providing a large working distance and a wide field of view. The bi-convex design, featuring two convex surfaces, ensures a low spherical aberration, enhancing the image quality and resolution.
The LB4545-A is coated with a broadband anti-reflection (AR) coating, specifically designed for the 350-700 nm range. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The coating also enhances the lens's durability and resistance to environmental factors, ensuring a long service life.
The lens's geometry includes a thickness of 2 mm at the edge and 2.6 mm at the center, providing structural rigidity while maintaining a low weight. The inner and outer radii are 0, indicating a symmetrical design, which further contributes to the lens's high optical performance.
