38-425 25.4mm Dia. x 100.0mm 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 25.4mm and a focal length of 100.0mm, making it suitable for a variety of applications that require high-quality imaging in the NIR II range.
The lens is made from N-BK7 Schott glass, a material known for its excellent optical properties and wide transparency range. This makes the lens ideal for use in applications that require high transmission and low dispersion.
The lens features a standard EDMM NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the NIR II range, improving transmission and reducing reflections. The coating is also durable, ensuring the lens maintains its performance over time.
The geometry of the lens is carefully designed to provide optimal performance. The lens has an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 1.42mm and a thickness at the center of 3mm. The radius of curvature of the first surface is 51.68mm, and the back focal length is 92.02mm.
