14PCX2500-1-1 25.4 mm Dia. x 2500 mm FL; Uncoated; Plano-Convex Lens

This is a Plano-Convex Lens, a type of spherical lens, sourced from Standa. The lens has a base shape of a circle and is designed for use in a variety of optical systems. The lens is made from n-bk7 Schott material, a popular choice for its high refractive index and low dispersion.

The lens has a diameter of 25.4 mm and a thickness at the edge of 2.9 mm. The thickness at the center of the lens is slightly greater at 3 mm. The effective focal length (EFL) of the lens is 2500 mm, making it suitable for use in systems where a long focal length is required.

The lens's radius of curvature (R1) is 1291.75 mm, while the inner and outer radii are both 0 mm. This specifications suggest that the lens has a relatively low curvature, which can be beneficial in reducing spherical aberration.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can make the lens more susceptible to environmental factors such as dust and moisture, but it also means that the lens does not introduce any additional chromatic aberration.

According to the vendor's website, this lens is currently in stock, making it a readily available option for those in need of a Plano-Convex lens with these specifications.
