This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as the 33-368-INK, is a spherical lens with a base shape of a circle, designed for use in the near-infrared (NIR) spectrum, specifically at a wavelength of 587.6nm.
The lens has a diameter of 25.0mm and a thickness at the edge of 2.82mm, while the center thickness is 3.2mm. The effective focal length (EFL) of the lens is 400.0mm, making it suitable for applications that require a longer focal length. The lens's front and back surfaces are coated with the EDM NIR-I standard curve coating, which enhances its performance in the NIR spectrum, specifically between 600-1050nm.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens. The first radius of curvature (R1) is 206.72mm, and the back focal length (BFL) is 397.89mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
