LD1613-A N-BK7 Bi-Concave Lens; Dia:25.4 mm; f=-100.0 mm ARC 350-700nm

The LD1613-A is a high-quality bi-concave lens from Thorlabs, designed with a base shape of a circle and a sub-type of spherical lens. This lens is constructed from N-BK7, a popular glass type from Schott, known for its excellent optical properties. The lens has a diameter of 25.4 mm and a thickness at the edge of 5.6 mm, while the center thickness is 4 mm.

The lens's effective focal length (EFL) is -100 mm, and the back focal length (BFL) is -101 mm, making it a powerful tool for focusing or diverging light. The radii of curvature for the first and second surfaces are -103.7 mm and 103.7 mm, respectively. The lens's design is optimized for a wavelength of 587.6 nm.

The LD1613-A comes with anti-reflection coatings on both the front and back surfaces, specifically designed for the ARC 350-700nm range. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens. The lens's shape is spherical, ensuring excellent optical performance.
