LC1315-B N-BK7 Plano-Concave Lens; Dia:2 in; f=-75.0 mm ARC 650-1050nm
The LC1315-B is a plano-concave lens, a type of spherical lens, featuring a negative focal length and a diameter of 2 inches. This lens is sourced from Thorlabs, a renowned vendor in the optical industry, and is currently in stock. The lens is made of N-BK7, a popular glass type from Schott, which is known for its excellent optical properties and versatility.
The LC1315-B has a base shape of a circle and a thickness of 13mm at the edge, reducing to 3.5mm at the center. It boasts an effective focal length (EFL) of -75mm, making it suitable for applications requiring a negative focal length. The lens's front and back surfaces are coated with tho b bbar, a broadband anti-reflection coating that enhances transmission in the 650-1050nm wavelength range.
This lens is designed for use in various optical systems, including imaging systems, beam shaping, and laser applications. Its high-quality materials, precise construction, and reliable performance make it a valuable addition to any optical setup.
