32-323 25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=50mm MgF2 400-700nm

The 32-323 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a 25 mm diameter, is designed for use in the visible light spectrum, specifically between 400-700nm. The lens boasts an effective focal length (EFL) of 50mm, making it suitable for a wide range of optical applications.

The lens is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott. These materials are carefully selected to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. The achromatic design ensures that the lens focuses both red and blue light to the same point, delivering sharp and clear images.

The lens features a multiplet geometry, with three radii (r1, r2, r3) and three thicknesses (thickness edge, thickness center, thickness center a) specified. The edge thickness is 8.79mm, while the center thickness is 9mm, and the thickness center a is 2.5mm. The inner and outer radii are 0, indicating a circular shape.

The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the overall performance of the lens. The coating is applied according to the standard curve, ensuring consistent and reliable performance.
