LC1258-C N-BK7 Plano-Concave Lens; Dia:25 mm; f=-75.0 mm ARC 1050-1700nm

The LC1258-C is a plano-concave lens with a diameter of 25 mm and a focal length of -75.0 mm, making it ideal for applications that require a diverging lens. This lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility.

The lens features a plano-concave geometry, meaning one side is flat while the other is curved inward. The curvature of the concave side is represented by a radius of -38.6 mm, and the back focal length is -77.3 mm. The lens has a central thickness of 3.5 mm and an edge thickness of 5.6 mm, providing structural integrity and resistance to damage.

The LC1258-C is coated with a broadband anti-reflection coating, suitable for wavelengths between 1050 nm and 1700 nm. This coating reduces surface reflections, enhancing transmission and improving overall system performance. The coating is applied to both the front and back surfaces of the lens.
