This is a Plano-Convex Lens, type of spherical lens, sourced from Edmund Optics. It features a circular base shape and is designed for use in the near-infrared (NIR) spectrum, specifically between 750 and 1550 nanometers. The lens has a diameter of 25.0mm and a focal length of 300.0mm, resulting in an effective focal length (EFL) of 175.0mm.
The lens's geometry includes a thickness of 2.63mm at the edge and 3.5mm at the center. The front and back surfaces have radii of 90.47mm and 0mm, respectively. The back focal length (BFL) is 172.85mm.
The lens is made from N-BK7 Schott glass, a common material for optical elements due to its excellent optical properties and wide transparency range. The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, which enhances its performance in the NIR spectrum.
This lens is a great option for applications that require high-quality imaging or light transmission in the NIR range, such as night vision, thermal imaging, or scientific research. It is currently in stock and available for immediate purchase.
