13-004 25 mm Dia. N-SK11/N-SF5 Mounted Achromatic Doublet; EFL=40mm MgF2 400-700nm
The 13-004 is a high-quality mounted achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of optical applications.
The lens features a 25 mm diameter and an effective focal length (EFL) of 40mm, providing a compact yet powerful optical solution. The achromatic doublet design, which combines two different types of glass (N-SK11 and N-SF5), helps to reduce chromatic aberration, ensuring sharp and clear images.
The lens is coated with EDM MgF2 standard curve coatings on both the front and back surfaces. This coating enhances the lens's light transmission capabilities and provides excellent protection against environmental factors, ensuring the lens's longevity and durability.
The lens's geometry includes a thickness of 7.08mm at the edge, a center thickness of 7.89mm, and a thickness of 3mm at the center a. The lens's inner and outer radii are 0mm, indicating a flat surface.
