45-408-INK 5 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=20mm MgF2 400-700nm
The 45-408-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 visible spectrum, specifically between 400-700nm, making it suitable for a wide range of optical applications.
The lens is a multiplet, meaning it is composed of multiple elements. The first element is made of N-BAF10 glass from Schott, while the second is made of N-SF10 glass, also from Schott. This combination of glasses helps to correct chromatic aberration, a common issue in optical systems, thereby improving the overall image quality.
The lens has an effective focal length (EFL) of 20mm, which is a common choice for many optical applications due to its versatility. The lens also features a standard MgF2 coating on both the front and back surfaces, which enhances its transmission in the visible spectrum.
The geometry of the lens includes a thickness of 2.38mm at the edge, with the center thickness being 1.61mm. The lens also features a curvature radius of 14.11mm for the first surface and -8.63mm for the second surface. The third surface has a curvature radius of -75.59mm.
According to the vendor's website, the lens is currently in stock, making it readily available for immediate use. For more detailed information, users are encouraged to visit the vendor's website using the provided weblink.
