49-923-INK 5 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=12.5mm MgF2 400-700nm
The 49-923-INK is a high-quality Achromatic Doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 5 mm diameter, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of optical applications.
The lens features a focal length (EFL) of 12.5mm, which is a common choice for many optical systems due to its versatility. The geometry of the lens includes a thickness of 2.78mm at the edge, a center thickness of 2.3mm, and a center thickness 'a' of 1mm. The lens's inner and outer radii are 0, suggesting a simple, circular shape.
The lens is composed of two types of glass, N-SSK8 and N-SF56, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, which enhances its transmission in the specified spectral range.
