47-734 20 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=35mm VIS 0° 425-675nm
The 47-734 is a high-quality achromatic doublet lens, boasting a 20 mm diameter and an effective focal length (EFL) of 35mm. This lens is specifically designed for the visible spectrum, covering a wavelength range of 425-675nm. Manufactured by Edmund Optics, this lens is part of their extensive catalog of optical elements, renowned for their precision and reliability.
The lens is constructed from two types of glass: S-BAH11 from Ohara and N-SF10 from Schott. This combination allows for superior chromatic correction, minimizing optical aberrations and ensuring high-resolution images. The lens features a standard anti-reflective coating on both the front and back surfaces, further enhancing its performance by reducing unwanted reflections and increasing transmission.
The lens geometry is carefully designed, with a central thickness of 7.33mm and edge thickness of 6.57mm. The radii of curvature are R1=24.24mm, R2=-15.96mm, and R3=-139.78mm, providing the lens with its unique optical properties. The lens is circular in shape, making it suitable for a wide range of applications.
