67-542 25.0mm Dia. x 25.0mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
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 25.0mm and a focal length of 25.0mm, making it a versatile choice for a variety of applications.
The lens is made from N-BK7 Schott glass, a material known for its excellent optical properties and wide transparency range. This makes the lens suitable for use in demanding optical systems. The lens features a plano-convex geometry, with a spherical shape and a convex surface. The radius of curvature for the front surface is 41.48mm, and the back focal length is 78.45mm.
The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, reducing reflections and increasing transmission. The coating also provides protection for the lens surface, helping to maintain its optical performance over time.
The lens has a center thickness of 2.35mm and an edge thickness of 1.13mm. The effective focal length (EFL) of the lens is 80mm. The lens does not have any inner or outer radii, as it is a simple plano-convex design.
