The 84-209 is a Plano-Convex spherical lens, characterized by its 6.0mm diameter and 15.0mm focal length. This lens is designed for use with a 1550nm wavelength, making it suitable for a range of applications in the near-infrared spectrum.
The lens is fabricated from n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for use in laser applications.
The lens features a laser-optimized V-coat coating on both the front and back surfaces. This coating is specifically designed to enhance the performance of the lens in laser applications, providing high reflectivity and low absorption at the specified wavelength.
The geometry of the lens includes a 1.4mm edge thickness and a 2.0mm center thickness. The inner and outer radii are both 0mm, indicating a flat surface on the non-curved side of the lens. The radius of curvature on the curved side is 7.75mm, and the back focal length is 13.68mm.
This lens is available from Edmund Optics, a leading provider of optical components. According to the vendor, the lens is currently in stock, ensuring quick and reliable delivery.
