The 47-689-INK is a high-quality achromatic doublet lens, boasting a 6.25 mm diameter and an effective focal length (EFL) of 10 mm. This lens is designed for use within the visible light spectrum, specifically catering to wavelengths between 425 and 675 nm.
Manufactured by Edmund Optics, this lens is constructed from two types of Schott glass: N-BAF10 and N-SF10. These materials are carefully selected to minimize chromatic aberration, ensuring clear, focused images. The lens features a standard curve coating on both the front and back surfaces, further enhancing its performance and durability.
The lens geometry is intricately designed, with a center thickness of 3.06 mm and edge thickness of 3.23 mm. The first and second radii are 6.98 mm and -4.35 mm respectively, while the third radius is -41.01 mm. The inner and outer radii are both zero, indicating a circular shape.
