LA1509-633 N-BK7 Plano-Convex Lens; Dia:1 in; f=100.0 mm 633nm V-Coat

The LA1509-633 is a Plano-Convex lens offered by Thorlabs, designed for use in a variety of optical systems. This lens is fabricated from N-BK7, a popular glass type known for its excellent optical properties, and is specifically designed for a wavelength of 587.6 nm.

The lens has a diameter of 1 inch (25.4 mm) and a focal length of 100.0 mm, making it suitable for applications that require a long focal length. The lens's geometry includes a thickness of 2 mm at the edge and 3.6 mm at the center, providing a solid structure for reliable performance.

The LA1509-633 features a front and back coating of tho 633 n-bk7 vc 633, which is a vacuum-deposited coating designed to enhance the lens's performance at the specified wavelength. This coating helps to reduce surface reflections and increase transmission, making the lens more efficient in light transmission.

The lens's shape is spherical, which is a common geometry for optical lenses due to its ease of manufacturing and good optical performance. The lens's inner and outer radii are 0, indicating a plano-convex design, where one side of the lens is flat, and the other side is curved.
