63-707 10 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=25mm VIS 0° 425-675nm
The 63-707 is a high-quality achromatic doublet lens, boasting a 10 mm diameter and an effective focal length of 25 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase through their website.
The lens is constructed from two types of Schott glass: N-BK7 and N-SF5. These materials are carefully selected to minimize chromatic aberration, a common issue in lenses where different wavelengths of light are focused at different points. By combining these materials, the 63-707 achieves superior image quality and color correction.
The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a central thickness of 3.5 mm. The edge thickness measures 3.76 mm, while the front and back radii are 15.37 mm and -11.1 mm respectively. The lens also features a -31.47 mm third radius, contributing to its achromatic properties.
The 63-707 is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's transmission and reduces reflection, thereby improving overall light efficiency.
