LB4453-C UV Fused Silica Bi-Convex Lens; Dia:1 in; f=500.0 mm ARC 1050-1700nm

The LB4453-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading vendor in the optical industry. This lens is specifically crafted from UV Fused Silica, a material with a wide transparency range, making it suitable for use across various applications. The lens boasts a diameter of 1 inch and a focal length of 500.0 mm, providing a large field of view and excellent image quality.

The lens's geometry is characterized by its spherical shape, with radii of curvature R1 and R2 measured at 459.7 mm and -459.7 mm respectively. This design ensures minimal spherical aberration, enhancing the overall optical performance. The lens has a central thickness of 2.4 mm and an edge thickness of 2 mm, providing robustness and durability.

The LB4453-C is coated with Thorlab's proprietary broadband anti-reflection coating, THo C Bbar, on both the front and back surfaces. This coating is designed to operate within the 1050-1700 nm wavelength range, reducing surface reflections and improving transmission efficiency.
