89-049 5.0mm Dia. x 10.0mm FL; Plano-Convex Lens Laser V-Coat 1550nm
The 89-049 is a 5.0mm diameter, plano-convex spherical lens with a focal length of 10.0mm, specifically designed for use with a 1550nm wavelength. 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 versatility. It has a refractive index of 1.5168 at 587.6nm and a Abbe number of 64.17, making it an ideal choice for a wide range of optical applications.
The plano-convex geometry of the lens, where one side is flat and the other is curved, provides a number of benefits. It minimizes spherical aberration, a common issue in optical systems, and focuses light to a single point. The lens has a center thickness of 1.64mm and an edge thickness of 1.0mm, providing a robust structure while maintaining a compact form factor.
The lens features a laser V-coat coating on both the front and back surfaces, specifically designed for use with a 1550nm wavelength. This coating enhances the lens's performance by reducing reflection and increasing transmission, ensuring optimal light propagation through the lens.
The item data also provides information about the lens's geometry, including the inner and outer radii, which are both 0mm. The back focal length (BFL) is 8.92mm, and the effective focal length (EFL) is 10mm. The radius of curvature (R1) is 5.17mm.
