LC1582-C N-BK7 Plano-Concave Lens; Dia:1 in; f=-75.0 mm ARC 1050-1700nm
The LC1582-C is a plano-concave lens with a diameter of 1 inch, featuring a focal length of -75.0 mm, specifically designed for use in the wavelength range of 1050-1700nm. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The plano-concave geometry, characterized by a flat front surface and a curved back surface with a radius of -38.6mm, is ideal for a variety of applications. The lens has a clear aperture of 1 inch, providing a wide field of view.
The LC1582-C features a center thickness of 3.5mm and an edge thickness of 5.6mm, ensuring durability and rigidity. The lens's effective focal length (EFL) is -75mm, making it suitable for applications requiring a long focal length. The back focal length (BFL) is -77.3mm, which is the distance from the back surface of the lens to the focal point.
The lens is coated with a broadband anti-reflection coating (ARC), specifically designed for the wavelength range of 1050-1700nm. This coating reduces unwanted reflections, improving transmission and overall performance. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from both sides.
