45-961 3.0mm Dia. x 4.5mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 45-961 is a Plano-Convex Spherical Lens, a type of spherical lens characterized by having one side flat and the other side curved. This particular lens has a diameter of 3.0mm and a focal length of 4.5mm, making it suitable for a variety of applications. The lens is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.
The lens is made from n-lasf44 schott, a material with specific optical properties that make it suitable for use in the 600-1050nm wavelength range. This makes the lens ideal for near-infrared (NIR) applications. The lens also features a coating on both the front and back surfaces, specifically the edm nir-i std curve coating. This coating is designed to enhance the lens' performance in the NIR range.
The lens has a thickness of 1.47mm at the edge and 1.8mm at the center. The back focal length (BFL) is 3.5mm, and the effective focal length (EFL) is also 4.5mm. The lens' inner and outer radii are both 0mm, indicating a symmetrical curvature.
