LA1251-B N-BK7 Plano-Convex Lens; Dia:25.0 mm; f=100.0 mm ARC 650-1050nm
The LA1251-B is a Plano-Convex lens, a type of spherical lens, sourced from the reputable vendor Thorlabs. This lens boasts a diameter of 25.0 mm and a focal length of 100.0 mm, making it suitable for a wide range of optical applications.
The lens is crafted from N-BK7, a high-quality glass material from Schott, renowned for its excellent optical properties. The geometry of the lens includes a thickness of 2.06 mm at the edge and 3.6 mm at the center, providing a solid structure for efficient light transmission.
The LA1251-B is coated with a broadband anti-reflection coating, specifically designed for the wavelength range of 650-1050nm. This coating, denoted as 'tho b bbar' for both the front and back surfaces, reduces surface reflections and enhances the overall transmission of light through the lens.
