38-421 25.4mm Dia. x 35.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. It is specifically designed for use in the Near-Infrared II (NIR II) spectrum, with a wavelength range of 750-1550nm, making it ideal for applications that require high-resolution imaging or sensing in this spectral range.

The lens has a diameter of 25.4mm and a focal length of 35.0mm, offering a substantial effective focal length (EFL) of 35mm. The lens is made from the high-quality material N-BK7 Schott, ensuring excellent optical performance and durability. The lens's geometry includes a thickness edge of 1.69mm and a thickness center of 6.9mm, providing a robust structure suitable for various applications.

The lens features a standard curve coating on both the front and back, specifically the EDM NIR-II STD curve. This coating enhances the lens's performance in the NIR II spectrum, reducing unwanted reflections and increasing transmission. The coating also provides protection against environmental factors, ensuring the lens maintains its optical performance over time.
