This is a Plano-Convex lens with a diameter of 25mm, sourced from the renowned optical components manufacturer, Holmarc Opto-Mechatronics. The lens is designed with a high-quality N-BK7 glass substrate, a popular choice in the industry due to its excellent optical properties.
The lens features a focal length (EFL) of 500mm, making it suitable for applications that require long-focus lenses. The plano-convex geometry, where one side is flat and the other curved, allows for efficient light collection and focusing. The lens has a thickness of 2mm at the edge, contributing to its robustness and durability.
The lens is coated with BBAR (Broadband Anti-Reflection) coating, optimized for the wavelength range of 400-700nm. This coating significantly reduces surface reflections, enhancing the overall transmission and improving the lens's performance in various applications.
The item data also indicates that the lens is spherical in shape, a common geometry for optical lenses due to its ease of manufacturing and excellent optical performance. The inner and outer radii are both zero, suggesting a symmetrical curvature on the convex side.
