LA4725-1550 25.4 mm Dia. UVFS Plano-Convex Lens; EFL=75mm 1550nm V-Coat

The LA4725-1550 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens features an EFL (Effective Focal Length) of 75.3 mm, which is a crucial parameter for determining the lens's magnification and field of view.

The lens's geometry includes a thickness of 2.1 mm at the edge and 4.4 mm at the center, providing a balanced profile for efficient light transmission. The lens's front surface has a radius of curvature of 34.5 mm, while the back surface is planar, contributing to its Plano-Convex shape.

The LA4725-1550 is made from UVFS material with a Mal-1965 Material ID. This material is well-suited for applications involving ultraviolet, visible, and near-infrared light. The lens is designed to operate at a wavelength of 587.6 nm, although its broadband anti-reflection coating allows for efficient operation across a wide spectral range.

This lens features a V-Coat coating on both the front and back surfaces. This coating, designated as tho v-ar-1550, is a broadband anti-reflection coating that reduces surface reflections and increases transmission. The coating is specifically designed for use at 1550 nm, making this lens ideal for applications in the telecommunications and sensing industries.
