The 32-917 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible light spectrum.
The lens features a 25mm diameter and a focal length of 200mm, providing a high level of optical precision. The doublet design, which combines two different types of glass, N-BK7 and N-SF5, helps to reduce chromatic aberration, ensuring sharp and clear images.
The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, further improving its optical performance.
The geometry of the lens includes a thickness of 11.56mm at the edge, a center thickness of 8.5mm, and a thickness of 4mm at the center 'a'. The lens's inner and outer radii are 0mm, indicating a simple, circular shape.
