67-500 12.0mm Dia. x 42.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a 67-500 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a diameter of 12.0mm and a focal length of 42.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). This design allows for efficient light gathering and focusing, making it ideal for imaging applications. The lens has a center thickness of 3.0mm and an edge thickness of 1.79mm, providing a robust and durable structure.
The 67-500 lens is coated with Edmund Optics' NIR-II standard curve coating on both the front and back surfaces. This coating enhances the lens' performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. The coating reduces surface reflections, improving light transmission and image quality.
The lens' shape is spherical, which is a common and versatile lens shape. The inner and outer radii are 0, indicating a simple spherical shape. The lens' effective focal length (EFL) is 30.0mm, which is a common value for this type of lens.
