67-559 25.0mm Dia. x 750.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-559 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.0mm and a focal length of 750.0mm, making it a versatile choice for various optical applications.
The lens is crafted from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures the lens delivers sharp, clear images with minimal chromatic aberration.
The 67-559 features a standard curvature coating on both the front and back surfaces, specifically the edm nir-ii std curve. This coating is designed to enhance the lens' performance in the near-infrared (NIR) spectrum, specifically between 750-1550nm. This makes the lens ideal for applications that require NIR transmission, such as thermal imaging, scientific research, and machine vision.
The lens has a thickness of 2.5mm at the edge and 3.0mm at the center. The effective focal length (EFL) is 300mm, and the back focal length (BFL) is 298.02mm. The lens' inner and outer radii are 0, indicating a simple, straightforward design that is easy to integrate into optical systems.
