38-385 35.0mm Dia. x 100.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm

The 38-385 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a diameter of 35.0mm and a focal length of 100.0mm, making it suitable for a wide range of optical applications.

The lens is crafted from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a planar surface on one side and a convex surface on the other. The edge thickness of the lens is 1.45mm, while the center thickness is 4.5mm, providing a solid and robust structure.

The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with a back focal length of 97.03mm and a radius of curvature of 51.68mm. The effective focal length (EFL) is 100.0mm, which is the distance from the lens's principal plane to the focal point.

The 38-385 lens is coated with EDM NIR-I std curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 600nm and 1050nm. The coating ensures high transmission, low reflectance, and improved durability, making the lens an excellent choice for NIR applications.
