LA1259-C N-BK7 Plano-Convex Lens; Dia:1 in; f=2500.0 mm ARC 1050-1700nm
The LA1259-C 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, is designed for use in a wide range of applications, particularly those requiring a long focal length and high precision.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. It features a plano-convex geometry, meaning one side is flat while the other is curved. This design allows for efficient light collection and focusing, making it ideal for imaging and beam shaping applications.
The LA1259-C has a focal length of 2500.0 mm, which is the distance at which it focuses light to a point. This long focal length makes it suitable for applications requiring high magnification or narrow fields of view. The lens's edge thickness is 2 mm, while its center thickness is 2.1 mm, providing robustness and stability.
The lens is coated with a broadband anti-reflection coating, specifically designed for the wavelength range of 1050-1700 nm. This coating reduces unwanted reflections, improving transmission and enhancing the performance of the lens in its intended wavelength range.
