This is a Plano-Convex Lens, sourced from Edmund Optics, designed for use in the Near-Infrared (NIR) spectrum, specifically for wavelengths between 750nm and 1550nm. The lens has a diameter of 12.0mm and a focal length of 54.0mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott glass, a common material in optical systems due to its excellent optical properties and high Abbe number. This ensures low dispersion and high homogeneity, which are crucial for maintaining image quality.
The lens features a standard EDMM NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, reducing reflection and increasing transmission. The coating is also standard curve, ensuring consistent performance across the specified wavelength range.
The geometry of the lens includes a thickness of 1.85mm at the edge and 2.7mm at the center. The lens's effective focal length (EFL) is 42mm, and the radius of curvature (R1) is 21.71mm. The back focal length (BFL) is 40.22mm, and both the inner and outer radii are 0mm.
