LF1015-B 25.4 mm Dia. N-BK7 Negative Meniscus Lens; EFL=-300mm 650-1050nm
The LF1015-B is a high-quality spherical lens from Thorlabs, featuring a concave-convex base shape and a circular geometry. With a diameter of 25.4 mm, this lens is designed to work with a wide range of optical systems. The lens has a center thickness of 3 mm and an edge thickness of 3.5 mm, providing a robust and durable structure.
The effective focal length (EFL) of this lens is -300mm, making it a negative meniscus lens. This type of lens is often used in applications where a reduced focal length is required. The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a symmetrical design.
The LF1015-B is made from N-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, making it suitable for a wide range of applications. The lens is coated with THo BBAR, a broadband anti-reflection coating that enhances its performance in the 650-1050nm wavelength range.
