32-886 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=150mm MgF2 400-700nm

The 32-886 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 50 mm diameter and an effective focal length (EFL) of 150mm, providing a substantial working distance for your optical setup. The lens is constructed from two types of glass, N-BAK4 and N-SF10, both from Schott, ensuring high-quality optical performance.

The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating is designed to provide high transmission across the visible spectrum, reducing unwanted reflections and increasing the overall efficiency of your optical system.

The geometry of the lens is carefully designed to minimize optical aberrations. The first and second radii (r1 and r2) are 96.85mm and -73.74mm respectively, while the third radius (r3) is -241.63mm. The lens has a center thickness of 9.5mm and edge thickness of 8.92mm, providing a robust and durable design.
