89-244 12mm Dia. x 48mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. The lens, identified as item number 89-244, boasts a 12mm diameter and a focal length of 48mm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a popular choice due to its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 49.14mm for both the front and rear surfaces. This geometry results in a high refractive power, ideal for focusing or collimating light beams.
The lens is coated with YAG-BBAR, a broadband anti-reflection coating that operates within the 500-1100nm wavelength range. This coating significantly reduces surface reflections, enhancing the overall transmission of the lens. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles.
The lens has a central thickness of 2.74mm and an edge thickness of 2mm, providing robustness and durability. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
