LA1560-A N-BK7 Plano-Convex Lens; Dia:0.5 in; f=25.0 mm ARC 350-700nm

The LA1560-A is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7, a popular optical glass known for its excellent optical properties, and is manufactured by Schott, a leading glass manufacturer.

The lens has a diameter of 0.5 inches (12.7 mm) and a focal length of 25.0 mm. The plano-convex design features a flat front surface and a curved back surface with a radius of curvature of 12.9 mm. This design results in a back focal length of 22.6 mm. The lens has a thickness of 1.8 mm at the edge and 3.5 mm at the center.

The LA1560-A is coated with Thorlabs' AR coating, which is designed to reduce reflection over the 350-700 nm wavelength range. This coating improves the lens's transmission, making it suitable for use in applications where high transmission is required.

The lens is spherical in shape, which is a common shape for optical lenses. This shape provides a simple and efficient way to focus light, making it a popular choice for many optical applications.
