This is a Plano-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens, identified as the 38-422, is designed with a 25.4mm diameter and a focal length of 40.0mm, making it suitable for a wide range of applications.
The lens is constructed from the high-quality material, N-BK7 Schott, which is known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for applications that require high image quality.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The curvature of the lens is defined by a radius of 20.67mm, which contributes to its focusing power. The lens has a central thickness of 5.9mm and an edge thickness of 1.54mm, providing a robust structure.
The lens is coated with the EDM NIR-II Standard Curve on both the front and back surfaces. This coating enhances the lens's performance in the near-infrared spectrum, specifically between 750nm and 1550nm. The coating ensures high transmission and low reflectance, making it ideal for applications such as night vision, thermal imaging, and spectral analysis.
