LA1237-A N-BK7 Plano-Convex Lens; Dia:30.0 mm; f=500.0 mm ARC 350-700nm
The LA1237-A is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7 Schott glass, a popular material known for its excellent optical properties and versatility.
The lens has a diameter of 30.0 mm and a thickness of 1.8 mm at the edge, increasing to 2.3 mm at the center. It boasts an effective focal length (EFL) of 500.0 mm, making it suitable for applications that require a longer focal length. The lens's front and back surfaces are coated with a broadband anti-reflection coating (ARC), specifically designed for the 350-700 nm wavelength range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
The LA1237-A's geometry is defined by a radius of curvature (R1) of 257.5 mm and a back focal length (BFL) of 496.8 mm. The lens's shape is spherical, a common and reliable choice for many optical systems.
