38-395 12.0mm Dia. x 50mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This 12.0mm diameter, 50mm focal length Plano-Convex lens, sourced from Edmund Optics, is specifically designed for use within the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens boasts an Anti-Reflection (AR) coating, known as "edm nir-ii std curve", on both its front and back surfaces, further enhancing its performance within the NIR range.

The lens's geometry includes a 1.29mm edge thickness and a 2.8mm center thickness, with an effective focal length (EFL) of 17.5mm. The lens's front surface has a radius of curvature (R1) of 9.05mm, and a back focal length (BFL) of 15.66mm. The lens is made from N-BK7 Schott glass, a common material for optical elements due to its excellent optical properties and availability.

This lens is part of a broader category of Spherical Lenses, which are characterized by their curved surfaces that evenly distribute the light across the entire aperture. The Plano-Convex design of this lens features one flat surface and one curved surface, which is beneficial for applications where a flat field is not required.

The item data indicates that this lens is in stock and available for immediate purchase, making it an ideal choice for those needing a reliable and high-performing NIR lens promptly.
