47-734-INK 20 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=35mm VIS 0° 425-675nm

The 47-734-INK is a 20 mm diameter achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is specifically engineered for visible light applications, with a wavelength range of 425-675nm. The lens boasts an effective focal length (EFL) of 35mm, making it suitable for a wide range of optical systems.

The lens is composed of two elements: S-BAH11 from Ohara and N-SF10 from Schott. These materials are carefully selected for their optical properties, contributing to the lens's high performance. The lens features a standard anti-reflection coating on both the front and back surfaces, which is specifically designed for visible light applications (edm vis-0 std curve).

The lens geometry is meticulously designed, with a center thickness of 7.33mm and an edge thickness of 6.57mm. The radii of curvature for the three surfaces are r1=24.24mm, r2=-15.96mm, and r3=-139.78mm. The lens is designed in a multiplet shape, which is often used in optical systems to correct chromatic aberrations and improve image quality.

According to the vendor's information, the lens is currently in stock, and the web link provided is valid. This makes the 47-734-INK an readily available option for those seeking a high-quality achromatic doublet lens for their optical systems.
