87-628 15.0mm Dia. x 22.5mm FL; Plano-Convex Lens Laser V-Coat 1550nm
This is a Plano-Convex Lens, sourced from the renowned optical components vendor, Edmund Optics. The lens has a diameter of 15.0mm and a focal length of 22.5mm, designed for use with a wavelength of 1550nm. The lens is made from n-sf5 Schott, a high-quality optical material known for its excellent transmission properties in the near-infrared region.
The lens features a Laser V-Coat 1550nm coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in laser applications, providing improved damage threshold and lower scatter. The coating also ensures high transmission and low reflectivity at the specified wavelength.
The geometry of the lens includes a thickness of 1.36mm at the edge and 3.35mm at the center. The lens's inner and outer radii are 0, indicating a flat surface on the incident side and a curved surface on the exit side. The back focal length (BFL) is 20.5mm, and the effective focal length (EFL) is 22.5mm.
