LD1464-B N-BK7 Bi-Concave Lens; Dia:25.4 mm; f=-50.0 mm ARC 650-1050nm
The LD1464-B is a high-quality bi-concave lens from Thorlabs, designed with a diameter of 25.4 mm and a focal length of -50.0 mm. This lens is made from N-BK7, a popular glass type from Schott, known for its excellent optical properties and wide transparency range.
The lens features a double-sided broadband anti-reflection coating (ARC), designed to operate between 650-1050nm. This coating reduces surface reflections, thereby increasing transmission and improving overall system performance.
The geometry of the lens includes a thickness of 6.1 mm at the edge and 3 mm at the center. The radii of curvature are -52 mm for the first surface and 52 mm for the second, resulting in a back focal length of -50.8 mm. The lens is spherical in shape, ensuring high-quality imaging and light control.
This lens is ideal for use in various applications, including beam shaping, focusing, and collimation. It is currently in stock, making it a readily available option for your optical system needs. For more information, please refer to the vendor's website provided.
