38-406 12.5mm Dia. x 50.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 38-406 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 12.5mm and a focal length of 50.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard curve coating, specifically the EDM NIR-II std curve, on both the front and back surfaces. This coating enhances the lens' performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications that require superior NIR transmission, such as night vision, thermal imaging, and spectral analysis.
The lens has a thickness of 1.14mm at the edge and 2mm at the center. The inner and outer radii are 0mm, indicating a uniform curvature. The back focal length is 43.68mm, and the effective focal length is 45mm. The lens' geometry and material properties make it an excellent choice for applications that require high-precision optics with excellent NIR transmission.
