45-883 18mm Dia. x 27mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm

The 45-883 is a high-quality double-convex lens, 18mm in diameter and 27mm in focal length, sourced from the renowned optical components manufacturer, Edmund Optics. This lens is specifically designed for use within the visible to near-infrared spectrum (VIS-NIR), catering to applications that require wavelengths between 400 and 1000 nanometers.

The lens boasts a base shape of a perfect circle, with a diameter of 18mm, and features a front and back spherical geometry. The front geometry has a radius of curvature (R1) of 27.08mm, while the back geometry has an R2 value of -27.08mm. This spherical design ensures excellent image quality and low distortion across the entire spectral range.

The 45-883 lens is made from the high-grade material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including high transmittance and low dispersion. This material makes the lens suitable for a wide range of applications, from imaging and metrology to beam shaping and spectroscopy.

The lens is coated with the EDM VIS-NIR 0SP 2002000 coating on both the front and back surfaces. This anti-reflection coating is designed to minimize surface reflections and increase transmission within the VIS-NIR spectrum, further enhancing the lens's performance.
