45-351 20 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=35mm MgF2 400-700nm
The 45-351 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens features a 20mm diameter and an effective focal length (EFL) of 35mm, providing a compact and efficient optical solution. The lens is constructed from two different materials, S-BAH11 from Ohara and N-SF10 from Schott, each selected for their specific optical properties. This combination helps to minimize chromatic aberration, a common issue in optical systems.
The lens surfaces are coated with Edmund Optics' standard MgF2 coating, which is applied to both the front and back surfaces. This coating is designed to enhance the lens's light transmission capabilities, reducing unwanted reflections and improving overall system performance.
The lens geometry is also a notable feature, with a center thickness of 7.33mm and edge thickness of 6.57mm. The lens also features three radii of curvature (r1, r2, and r3) that are precisely engineered to provide the best possible optical performance.
