38-432 25.4mm Dia. x 150.0mm 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 the wavelength range of 750-1550nm. The lens has a diameter of 25.4mm and a focal length of 150.0mm, making it suitable for a variety of optical applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance and low dispersion, making it ideal for use in imaging and laser systems.
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 spectrum, reducing reflection and increasing transmission.
The geometry of the lens includes a thickness of 1.95mm at the edge and 3mm at the center. The inner and outer radii are both 0mm, indicating a flat surface on the non-curved side of the lens. The first radius of curvature (R1) is 77.52mm, and the back focal length (BFL) is 148.02mm.
