LC1315-C N-BK7 Plano-Concave Lens; Dia:2 in; f=-75.0 mm ARC 1050-1700nm
The LC1315-C is a plano-concave lens, a type of spherical lens, featuring a negative focal length, manufactured by Thorlabs. This lens is designed for use within a broad spectral range, from 1050nm to 1700nm, making it suitable for a wide variety of applications.
The lens is constructed from N-BK7 glass, a popular material in optical systems due to its excellent optical properties. The lens has a diameter of 2 inches (50.8mm) and a thickness of 13mm at the edge, tapering down to 3.5mm at the center. The negative focal length of the lens is -75mm, and the back focal length is -77.3mm.
The lens features anti-reflection coatings on both the front and back surfaces, specifically designed for the wavelength range of 1050nm to 1700nm. These coatings help to minimize surface reflections, thereby increasing the amount of light transmitted through the lens.
