13-011 25 mm Dia. N-BK7/N-SF5 Mounted Achromatic Doublet; EFL=150mm MgF2 400-700nm
This is a 13-011 25 mm Dia. N-BK7/N-SF5 Mounted Achromatic Doublet, available from Edmund Optics. The lens is characterized by its EFL (Effective Focal Length) of 150mm, specifically designed for the spectral range of 400-700nm.
The lens is a multiplet, meaning it is composed of multiple optical elements. In this case, it is made up of two different materials: N-BK7 and N-SF5, both from Schott. 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 has a diameter of 25mm and a thickness at the edge of 6.65mm. The inner and outer radii are 0, and the thickness at the center is 5.7mm. The thickness at the center 'a' is 2.2mm. The lens features a standard MgF2 coating on both the front and back surfaces, which provides excellent optical performance across the specified spectral range.
