87-920 5.0mm Dia. x 30.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 87-920 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 5.0mm and a focal length of 30.0mm, making it suitable for a variety of optical applications. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.
The lens features a front and back coating of EDM NIR-I STD Curve, which is designed for use in the near-infrared spectrum, specifically between 600-1050nm. This coating enhances the lens's performance in this spectrum by reducing reflection and increasing transmission.
The geometry of the lens includes a thickness of 1.4mm at the edge and 1.6mm at the center. The lens's effective focal length (EFL) is 30.0mm, and its back focal length (BFL) is 28.95mm. The lens's inner and outer radii are 0mm, indicating a plano surface on the back side of the lens.
The lens's type, Sub Type, Base Shape, and coating make it a versatile component for various optical systems. Its NIR capabilities, coupled with its high-quality coating, make it an excellent choice for applications in the near-infrared spectrum.
