89-218 6mm Dia. x 12mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. The lens, with a diameter of 6mm and a focal length of 12mm, is designed for use in a wide range of optical applications, particularly those requiring broadband anti-reflection (BBAR) coating.
The lens is made from the high-grade material, n-BK7 Schott, which is known for its excellent optical properties, including high transmittance and low auto-fluorescence. The base shape of the lens is circular, ensuring a wide field of view and minimal distortion.
The Double-Convex geometry of the lens (with radii of curvature R1 and R2 being 11.98mm and -11.98mm respectively) provides a high degree of focusing power, making it ideal for use in imaging systems, beam shaping, and other applications where precise optical control is required.
The lens features a YAG-BBAR coating on both the front and back surfaces, designed to operate within the wavelength range of 500-1100nm. This coating significantly reduces surface reflections, thereby improving transmission and minimizing losses. The coating also provides excellent environmental stability, ensuring the lens maintains its performance even in harsh conditions.
