45-028 25.0mm Dia. x -50 FL; Uncoated; Plano-Concave Lens
The 45-028 is a 25.0mm diameter Plano-Concave lens with a focal length of -50 from Edmund Optics. This lens is uncoated and features a base shape of circle. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The geometry of the lens includes a thickness edge of 6.33 and a thickness center of 3.5. The effective focal length (EFL) is -50, and the radius of curvature (R1) is -25.84. The back focal length (BFL) is -52.31. The lens does not have any coating, which means it is in its raw state and will have high reflection losses.
This lens is designed to work with a wavelength of 587.6 nm. It is a spherical lens, which means it has the same curvature throughout its surface. The lens is ideal for use in applications where a concave lens is required, such as in cameras, projectors, and other optical systems.
Please note that the lens is uncoated, which means it may not perform optimally in high-intensity light situations. It is recommended to use an anti-reflective coating for such applications. The lens is in stock and available for immediate shipping.
