LD1464-C N-BK7 Bi-Concave Lens; Dia:25.4 mm; f=-50.0 mm ARC 1050-1700nm
The LD1464-C is a high-quality bi-concave lens offered by Thorlabs, a leading global manufacturer of photonics components. This lens, designed from the renowned N-BK7 glass by Schott, is characterized by its concave-concave base shape and circular geometry.
The lens has a diameter of 25.4 mm and a thickness of 6.1 mm at the edge, tapering down to 3 mm at the center. It boasts an effective focal length (EFL) of -50 mm, making it suitable for a wide range of applications where negative focal lengths are required. The radii of curvature for the first and second surfaces are -52 mm and 52 mm, respectively, resulting in a back focal length (BFL) of -50.8 mm.
The LD1464-C lens is coated with Thorlabs' proprietary AR coating, designed to operate within the 1050-1700 nm wavelength range. This anti-reflective coating ensures high transmission and minimal loss of light, making it ideal for use in laser applications and other settings where efficient light transmission is crucial.
