67-454 5.0mm Dia. x 7.5mm FL; NIR II Coated; Plano-Convex Lens NIR II 750-1550nm

This 5.0mm diameter x 7.5mm focal length Plano-Convex lens, sourced from Edmund Optics, is specifically designed for use in the near-infrared (NIR) spectrum, covering the wavelength range of 750-1550nm. The lens is made from n-sf11 Schott material, a popular choice for its high refractive index and low dispersion, making it ideal for applications that require high resolution and minimal chromatic aberration.

The lens features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-II coating. This coating enhances the lens's performance in the NIR spectrum, improving transmission and reducing reflection. The coating is designed to meet the specific demands of NIR applications, ensuring optimal performance and longevity.

The lens geometry includes a 1.34mm edge thickness and a 1.9mm center thickness, with a 5.89mm radius on the curved surface and a 6.43mm back focal length. The lens is spherical in shape, a common choice for its simplicity and versatility. Despite its compact size, this lens offers a substantial 7.5mm effective focal length, making it suitable for a wide range of applications.
