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.
