LA1461 N-BK7 Plano-Convex Lens; Dia:1 in; f=250.0 mm Uncoated

The LA1461 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 1 inch and a focal length of 250.0 mm, is designed for use in a wide range of optical systems, including beam shaping, focusing, and imaging applications.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, is characterized by a high refractive index and low dispersion, making it ideal for applications that require high image quality and minimal chromatic aberration.

The Plano-Convex design of this lens features a flat front surface and a curved back surface. This design is often used to minimize spherical aberration, a common optical distortion that can degrade image quality. The lens has a center thickness of 2.6 mm and an edge thickness of 2 mm, providing a robust and durable construction.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses at the air-glass interfaces, it can also make the lens more cost-effective and suitable for applications where such coatings are not necessary.

According to the vendor's website, this lens is currently in stock, indicating its availability for immediate purchase and delivery. The website also provides further technical specifications and application notes, which can be valuable resources for users considering this lens for their optical systems.
