32-325 25 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=75mm MgF2 400-700nm
The 32-325 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 25 mm diameter, is designed for use in the visible spectrum, specifically optimized for the 400-700nm range. The lens is a multiplet, composed of two distinct materials, N-BK7 and N-SF5, both from Schott, a leading manufacturer of optical glass.
The lens features an effective focal length (EFL) of 75mm, making it suitable for a wide range of optical applications. The geometry of the lens is carefully crafted, with a thickness of 6.97mm at the edge and 7mm at the center, ensuring optimal light transmission and minimal distortion. The inner and outer radii of the lens are 0, indicating a symmetrical design that further enhances its optical performance.
The 32-325 lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating is designed to provide excellent transmission in the visible spectrum, further enhancing the lens's performance in its intended application range.
The lens is currently in stock and available for immediate purchase. For more information, including detailed specifications and pricing, please refer to the product's webpage on the Edmund Optics website.
