The LA2039-A is a 3 mm diameter Plano-Convex lens made from N-SF11 Schott glass, featuring an effective focal length (EFL) of 9mm and designed for use within the wavelength range of 350-700nm. This lens is sourced from Thorlabs, a leading global manufacturer of photonics equipment.
The lens has a spherical geometry, with a thickness of 1.2mm at the edge and 1.5mm at the center. The front and back surfaces are coated with a broadband anti-reflection coating (tho a bbar), which reduces surface reflections and increases transmission. The lens's shape is circular, and it has no inner or outer radius, indicating a uniform curvature across the surface.
The LA2039-A is a versatile lens suitable for a wide range of optical applications. Its compact size and high transmission make it an ideal choice for beam shaping and focusing in compact systems. The lens's broad wavelength range also makes it suitable for use in multi-spectral applications.
