HO-BVL50-20 50mm Dia. N-BK7 Double-Concave Lens; EFL=-1000mm Uncoated
This is a HO-BVL50-20 50mm diameter N-BK7 double-concave lens, with a focal length of -1000mm, making it a powerful tool for optical systems that require strong negative magnification. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for its high-quality optical components.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. This material, also known as Schott BK7, has a high refractive index and low dispersion, making it ideal for a wide range of applications.
The lens geometry is spherical, with a base shape of a circle. The diameter of the lens is 50mm, and the center thickness is 2.5mm. The first radius of curvature (R1) is -1043.762884, and the second radius of curvature (R2) is 1043.762884. The lens does not have any coating, which means it is uncoated.
The lens is designed to work with a wavelength of 587.6nm. It is important to note that the lens is uncoated, which means it may not perform optimally in environments with high levels of light scattering or where anti-reflective properties are required. However, it can be a cost-effective solution for applications where such properties are not critical.
