38-394 12.0mm Dia. x 25mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm
The 38-394 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.0mm diameter and a 25mm focal length, making it suitable for a wide range of applications. The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the near-infrared (NIR) region.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other is curved (convex). The curvature of the convex side is defined by a radius of 9.81mm, and the lens has a central thickness of 2.7mm. The edge thickness is 1.33mm, providing structural integrity and resistance to damage.
The 38-394 lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces. This coating enhances the lens's performance in the NIR region, specifically between 750nm and 1550nm, by reducing reflection and increasing transmission. The coating also provides protection against environmental factors, ensuring the lens maintains its performance over time.
