67-446 4.0mm Dia. x 4.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-446 is a Plano-Convex lens, a type of spherical lens, with a diameter of 4.0mm and a focal length of 4.0mm. This lens is sourced from Edmund Optics and is currently in stock. It is designed for use in the near-infrared spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made from n-lasf44 Schott, a material known for its excellent optical properties in the near-infrared range. It features a standard NIR II coating on both the front and back surfaces, which enhances its performance in the NIR spectrum.
The geometry of the lens includes a thickness of 1.0mm at the edge and 1.7mm at the center. The inner radius is 0, and the outer radius is also 0, indicating a flat surface on the opposite side of the convex surface. The back focal length (BFL) is 3.06mm, and the effective focal length (EFL) is 4.0mm.
This lens is a part of our extensive catalog of optical elements, providing users with a wide range of options for their optical simulation needs. The detailed parameters and specifications of the lens make it a suitable choice for users looking for components with similar properties.
