LA1256 N-BK7 Plano-Convex Lens; Dia:2 in; f=300.0 mm Uncoated

The LA1256 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of precision photonics. This lens, with a diameter of 2 inches, is designed for use in a variety of optical systems, offering a focal length of 300.0 mm.

The lens is made of N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision applications due to its low coefficient of thermal expansion and high homogeneity. The N-BK7 Schott designation indicates that the glass meets the stringent quality standards set by Schott, a renowned glass manufacturer.

The Plano-Convex design of this lens features a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 154.5 mm, which contributes to its specific optical properties. The lens has a central thickness of 5.1 mm and an edge thickness of 3 mm, providing structural integrity and resistance to deformation.

The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where a natural lens surface is preferred. However, it's important to note that uncoated lenses can be more susceptible to environmental factors such as dust and moisture, and may require more frequent cleaning.

The LA1256 N-BK7 Plano-Convex Lens is currently in stock, according to the vendor's website. It's a versatile and reliable choice for a wide range of optical applications, offering excellent optical performance and robust construction.
