LA1256-B N-BK7 Plano-Convex Lens; Dia:2 in; f=300.0 mm ARC 650-1050nm
The LA1256-B is a Plano-Convex lens, a type of spherical lens, sourced from the reputable optical components manufacturer, Thorlabs. This lens is characterized by its circular base shape and is designed for use in the 650-1050nm wavelength range.
The lens has a diameter of 2 inches (50.8mm) and a thickness of 3mm at the edge, which gradually increases to 5.1mm at the center. This design gives it an effective focal length (EFL) of 300mm, making it suitable for a variety of optical applications.
The LA1256-B is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens's front and back surfaces are coated with a broadband anti-reflection coating (ARC), specifically designed for the 650-1050nm wavelength range. This coating helps to minimize surface reflections, thereby improving transmission and overall system performance.
According to the vendor's website, the LA1256-B is currently in stock, indicating its availability for immediate purchase and use. This lens, like other Thorlabs products, is expected to meet high standards of quality and reliability, making it a trusted choice for many optical applications.
