LB1471-C N-BK7 Bi-Convex Lens; Dia:1 in; f=50.0 mm ARC 1050-1700nm

The LB1471-C is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens boasts a diameter of 1 inch (25.4 mm) and a focal length of 50.0 mm, making it suitable for a wide range of optical applications.

The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The N-BK7 material ensures high transmission and low dispersion, making it an ideal choice for applications that require high-precision optics.

The LB1471-C features a unique anti-reflection coating, designed to operate within the 1050-1700nm wavelength range. This coating significantly reduces surface reflections, thereby improving the overall efficiency and performance of the lens.

The lens geometry is another notable feature. It has a center thickness of 2.2 mm and an edge thickness of 2 mm, providing excellent mechanical stability and resistance to stress. The lens also has a clear aperture of 25.4 mm, allowing for a wide range of optical beam sizes.

In terms of shape, the LB1471-C is a spherical lens with a convex-convex design. This shape provides a smooth and regular curvature, minimizing optical aberrations and ensuring high-quality imaging.
