14BCV75-1-2 25.4 mm Dia. x 75 mm FL; Uncoated; Double-Concave Lens

The 14BCV75-1-2 is a double-concave lens with a base shape of a circle, designed and manufactured by Standa. This lens is part of the Spherical Lens (Concave-Concave) sub-type, featuring a diameter of 25.4 mm and a focal length of 75 mm. The lens is uncoated, providing a clear, unaltered view of the light passing through it.

The lens's geometry is meticulously crafted, with a thickness of 5 mm at the edge and 3.8 mm at the center. The inner and outer radii are both zero, indicating a symmetrical curvature. The effective focal length (EFL) is 75 mm, which is the distance from the lens's center to the point where the light rays converge or diverge.

The lens is made from UVFS Mal-1965, a material specifically designed for optical applications. It is optimized for use with a wavelength of 355 nm, making it ideal for various applications in this spectrum.
