67-456 5.0mm Dia. x 12.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. It is specifically designed for use in the near-infrared (NIR) spectrum, with a wavelength range of 750-1550nm. The lens has a diameter of 5.0mm and a focal length of 12.0mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and wide transparency range. The front and back surfaces of the lens are coated with EDM NIR-II STD Curve, a specialized coating that enhances its performance in the NIR spectrum.
The geometry of the lens includes a thickness of 1.25mm at the edge and 1.77mm at the center. The inner and outer radii are both 0mm, indicating a flat surface on the side opposite the convex surface. The effective focal length (EFL) is 12mm, and the back focal length (BFL) is 10.83mm.
This lens is a versatile and high-performing option for applications in the NIR spectrum. Its Plano-Convex design, high-quality glass material, and specialized coating make it an excellent choice for a wide range of optical systems.
