The 38-377 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers. This lens boasts a diameter of 25.4 millimeters and a focal length of 40 millimeters, making it suitable for a wide range of optical applications.
The lens is constructed from N-BK7 Schott glass, a popular material in optical systems due to its excellent optical properties and versatility. The front and back surfaces of the lens are coated with EDM NIR-I Standard Curve coatings, designed to enhance performance within the NIR spectrum.
The lens geometry includes an edge thickness of 1.54 millimeters and a center thickness of 5.9 millimeters. The inner radius is zero, while the outer radius is also zero, indicating a plano surface on the non-curved side of the lens. The lens's effective focal length (EFL) is 40 millimeters, and the radius of curvature (R1) is 20.67 millimeters. The back focal length (BFL) is 36.11 millimeters.
This lens is available for purchase directly from the vendor, as indicated by the valid in-stock status on the associated web link. With its specifications and coatings, the 38-377 is an excellent choice for those requiring a high-performing NIR lens for their optical system.
