49-925 6.25 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=17.5mm MgF2 400-700nm

The 49-925 is a high-quality Achromatic Doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 6.25 mm diameter and an effective focal length (EFL) of 17.5 mm, making it suitable for a wide range of optical applications.

The lens is composed of two distinct materials, N-SSK8 and N-SF56, both from Schott, a leading manufacturer of optical glass. This combination helps to correct chromatic aberration, a common issue in optical systems, thereby enhancing the overall image quality.

The 49-925 features a sophisticated geometry, with a thickness of 3.18 mm at the edge and 2.75 mm at the center. The lens also has a center thickness 'a' of 1, and its inner and outer radii are optimized for optimal performance.

The lens is coated with Edmund Optics' standard MgF2 coating, which is designed to provide high transmission in the 400-700 nm spectral range. This coating enhances the lens's light transmission capabilities, making it ideal for applications that require high-resolution imaging.

The 49-925 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website, linked below.
