67-435 2.5mm Dia. x 2.5mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-435 is a Plano-Convex Spherical Lens, 2.5mm in diameter and 2.5mm focal length, sourced from Edmund Optics. This lens is designed for use in the near-infrared (NIR) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens is made from n-lasf9 Schott, a material known for its excellent optical properties in the NIR range. It features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating, which is designed to enhance performance in the NIR spectrum.
The geometry of the lens includes a 0.39mm thickness at the edge and a 0.8mm thickness at the center. The inner and outer radii are 0, indicating a flat surface on the incident side and a curved surface on the exit side. The effective focal length (EFL) is 2.5mm, and the back focal length (BFL) is 2.07mm.
This lens is part of a larger catalog of optical elements available at 3DOptix, designed to provide users with a wide range of options for their optical simulation needs. The item data provided ensures that users have access to comprehensive information, enabling them to make informed decisions when selecting components for their specific applications.
