89-236 10mm Dia. x 40mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a high-quality double-convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, identified as item number 89-236, boasts a 10mm diameter and a focal length of 40mm, making it suitable for a wide range of applications.
The lens is made from Schott's n-BK7 glass, a popular material in the optical industry due to its excellent optical properties and high transmittance in the visible spectrum. The lens's geometry includes an edge thickness of 1.89mm and a center thickness of 2.5mm, contributing to its robustness and durability.
The lens features a broadband anti-reflection (BBAR) coating, specifically YAG-BBAR, designed to operate within the 500-1100nm wavelength range. This coating significantly reduces surface reflections, enhancing the lens's overall transmission and improving its performance in various applications, particularly in laser systems and imaging applications.
The lens's base shape is circular, and its shape is spherical, which is a common design for lenses due to its ease of manufacturing and good optical performance. The inner and outer radii are not specified, indicating that they are not critical to the lens's performance or design.
