62-480 6.25 mm Dia. N-BAF10/N-SF10 Negative Achromatic Doublet; EFL=-25mm VIS 0° 425-675nm

The 62-480 is a high-quality negative achromatic doublet lens, boasting a 6.25 mm diameter and a focal length of -25 mm. This lens is meticulously crafted from two distinct materials, N-BAF10 and N-SF10, both sourced from the renowned optical glass manufacturer Schott.

The lens is designed to correct chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. The achromatic doublet structure ensures that the lens focuses both red and blue light at the same point, delivering sharp and clear images.

The 62-480 features a sophisticated geometry, with a thickness of 3.27 mm at the edge and varying radii (r1=-17.57, r2=11.48, r3=109.44) to optimize its optical performance. The lens also has a central thickness of 1 mm and an additional thickness of 2 mm at the front, enhancing its structural integrity.

This lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating is specifically designed to optimize its performance within the visible light spectrum, from 425 to 675 nm. The coating enhances the lens's light transmission, reduces surface reflections, and protects the lens from environmental hazards, ensuring longevity and maintaining its optical performance.

The 62-480 is available from Edmund Optics and is currently in stock, making it an ideal choice for users seeking a reliable and high-performing lens for their optical systems.
