67-527 18.0mm Dia. x 27.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 67-527 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts an 18.0mm diameter and a focal length of 27.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating is designed to enhance the lens' performance in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm. This makes the lens ideal for applications that require high-quality imaging or data collection in the NIR range, such as night vision, thermal imaging, or spectral analysis.
The lens has a center thickness of 3mm and an edge thickness of 2.45mm, providing a balance between durability and optical performance. The inner and outer radii are 0mm, indicating a uniform curvature across the lens surface. The effective focal length (EFL) of the lens is 100mm, which, combined with its diameter and thickness, contributes to its high optical quality.
