LB01-25-250 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=250mm Uncoated

This is the LB01-25-250, a 25.4 mm diameter Double-Convex lens made from N-BK7 glass, sourced from CeNing Optics. The lens is uncoated and has a focal length of 250mm, making it suitable for a wide range of optical applications.

The lens features a base shape of a circle, with a thickness of 2mm at the edge and 2.62mm at the center. The inner and outer radii are both 0, indicating a symmetrical design. The radii of curvature for the first and second surfaces are 258.9mm and -258.9mm respectively, which contributes to its double-convex geometry.

The lens is made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. It has a refractive index of approximately 1.5168 at the wavelength of 546.1nm. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website provided in the item data.
