LA1779 N-BK7 Plano-Convex Lens; Dia:2 in; f=1000.0 mm Uncoated

The LA1779 N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading global vendor in the field of optics and photonics. This lens, with a diameter of 2 inches, is designed for use in a wide range of applications, from research and development to industrial and commercial settings.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. It is a spherical lens, specifically a plano-convex lens, which means it has one flat surface and one curved surface. The curvature of the lens is defined by a radius of 515.1 mm, and the back focal length (BFL) is 994.3 mm. The effective focal length (EFL) of this lens is 1000 mm, making it suitable for use in systems that require a long focal length.

The lens has a thickness of 3 mm at the edge and 3.6 mm at the center. The inner and outer radii are both 0, indicating that the lens is uniformly curved. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces.

According to the vendor's website, this lens is in stock, indicating that it is readily available for purchase and delivery. The website also provides further technical specifications and application notes, which may be useful for those considering this lens for their optical systems.
