The 65-304 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 2.5mm and a focal length of 5.0mm, is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm.
The lens is made from n-lasf9 schott, a material known for its optical properties within this spectrum. The front and back surfaces of the lens are coated with edm visnir0sp2002000, a coating that enhances its performance within the visible to near-infrared range.
The geometry of the lens is defined by its edge thickness of 0.61mm and center thickness of 0.8mm. The lens's inner and outer radii are 0, indicating a flat inner surface and a curved outer surface. The back focal length (BFL) is 4.57mm, and the effective focal length (EFL) is 5mm.
The lens's web links are valid and indicate that it is currently in stock, making it readily available for immediate use. This lens is an excellent choice for applications that require a small, high-performance lens within the visible to near-infrared spectrum.
