32-311 12.5 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=25mm MgF2 400-700nm
The 32-311 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 12.5 mm diameter and a focal length of 25mm. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF10, which are renowned for their excellent optical properties. The N-BAF10 is used for the first element, while the N-SF10 is used for the second. This combination helps to correct chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly in the 400-700nm range. The center thickness of the lens is 5mm, with a slight asymmetry towards the edge (4.9mm). The inner and outer radii are not specified, indicating that they are likely not critical to the lens's performance.
The 32-311 is currently in stock and available for purchase from the Edmund Optics website. With its high-quality materials, advanced design, and reliable performance, this lens is an excellent choice for a wide range of optical applications.
