LA1253-C N-BK7 Plano-Convex Lens; Dia:25.0 mm; f=200.0 mm ARC 1050-1700nm
The LA1253-C is a high-quality plano-convex lens offered by Thorlabs, a leading global manufacturer of photonics components. This lens, designed from the renowned N-BK7 Schott glass, is specifically engineered for use within the wavelength range of 1050-1700nm, making it an excellent choice for near-infrared applications.
The lens boasts a diameter of 25.0 mm and a focal length of 200.0 mm, providing a substantial effective focal length (EFL) of 200.0 mm. The plano-convex design features a radius of curvature (R1) of 103 mm, yielding a back focal length (BFL) of 198.1 mm. The lens's edge thickness measures 2.04 mm, while the center thickness is 2.8 mm, ensuring robustness and durability.
The LA1253-C is equipped with an anti-reflection coating (ARC) on both the front and back surfaces, specifically designed for the 1050-1700nm wavelength range. This coating significantly reduces surface reflections, enhancing overall transmission and improving overall system performance.
