48-778-INK 25.0mm Dia. x 200.0mm FL; NIR I; Inked; Plano-Convex N-K5 Lens NIR I 600-1050nm
The 48-778-INK is a Plano-Convex Spherical Lens, sourced from the renowned optical component vendor, Edmund Optics. This lens boasts a diameter of 25.0mm and a focal length of 200.0mm, making it a versatile choice for various optical applications.
The lens is crafted from N-K5 Schott glass, a material known for its excellent optical properties, particularly in the near-infrared (NIR) spectrum. The NIR-I coating on both the front and back surfaces of the lens enhances its performance in the 600-1050nm wavelength range, ensuring optimal transmission and minimal reflection.
The lens features a planar front surface and a convex rear surface, with a central thickness of 3.2mm and an edge thickness of 2.45mm. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface. The lens's effective focal length (EFL) is 200.0mm, and the back focal length (BFL) is 197.9mm, providing a long focal length that can be beneficial in many applications.
The lens is inked, which is a process that adds a dye or pigment to the lens to enhance its visibility or to mark it for identification purposes. This does not affect the lens's optical performance but can be useful in certain applications.
