89-206 3mm Dia. x 4.5mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-206 is a high-quality spherical lens, boasting a double-convex design and a 3mm diameter. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock. The lens features a focal length of 4.5mm, making it suitable for a wide range of optical applications.
The lens is constructed from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. The base shape of the lens is circular, and it has a thickness of 1.47mm at the edge and 2mm at the center. The effective focal length (EFL) is 3.78mm, and the radii of curvature are 4.29mm for both the front and back surfaces.
The 89-206 lens is coated with YAG-BBAR, a highly durable and efficient coating that enhances its performance in the spectral range of 500-1100nm. This coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and reducing unwanted reflections.
