LE1076-B 50.8 mm Dia. N-BK7 Positive Meniscus Lens; EFL=100mm 650-1050nm
The LE1076-B is a spherical lens with a base shape of a circle, sourced from the reputable vendor Thorlabs. This lens is a positive meniscus type, featuring a diameter of 50.8 mm and a thickness at the edge of 1.1 mm. The center thickness is 9.7 mm, and it has an effective focal length (EFL) of 100 mm. The lens is designed for use within the wavelength range of 650-1050 nm.
The curvature of the lens is defined by two radii: the first radius (R1) is 30.3 mm, and the second radius (R2) is 65.8 mm. The back focal length (BFL) is 88.8 mm. The lens is made of N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties.
The LE1076-B lens is coated with THo BBAR on both the front and back surfaces to enhance its performance. This coating reduces reflection and increases transmission, making the lens suitable for various applications. The lens's shape is spherical, which is a common choice for many optical systems due to its ease of manufacturing and good optical performance.
According to the vendor's website, the LE1076-B is currently in stock, indicating its availability for immediate purchase and use. This lens is a reliable choice for applications that require a positive meniscus lens with specific curvature radii, a defined EFL, and a particular material and coating.
