67-568 30.0mm Dia. x 40.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
This is a Plano-Convex lens, sourced from Edmund Optics, designed for use in the near-infrared spectrum, specifically for wavelengths between 750nm and 1550nm. The lens has a diameter of 30.0mm and a focal length of 40.0mm, making it a versatile choice for a variety of applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This makes it ideal for use in high-precision applications where clarity and accuracy are paramount.
The lens features a standard NIR II coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the near-infrared spectrum, reducing reflection and increasing transmission. The coating is applied using Edmund Optics' standard curve, ensuring consistent performance and reliability.
The geometry of the lens is carefully designed to optimize its performance. The lens has an inner radius of 0mm and an outer radius of 0mm, with a center thickness of 4mm and an edge thickness of 2.21mm. The lens's effective focal length (EFL) is 88.9mm, and its back focal length (BFL) is 86.26mm.
