89-051 5.0mm Dia. x 15.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm
The 89-051 is a 5.0mm diameter, plano-convex spherical lens with a focal length of 15.0mm, designed for use with a wavelength of 1550nm. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The plano-convex geometry, where one side is flat and the other curved, is ideal for collimating or focusing light. The lens has a center thickness of 1.6mm and an edge thickness of 1.19mm, providing robustness and durability.
The lens features a laser-optimized V-coat coating on both the front and back surfaces. This coating is specifically designed for use with 1550nm wavelengths, ensuring high transmission and low reflection. The coating also provides excellent environmental stability, making it suitable for use in various applications.
The lens has an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature. The back focal length is 13.94mm, which is the distance from the lens's rear surface to its focal point.
