PAC043 25.4 mm Dia. N-BAF10/N-SF10 Visible Achromatic Doublet; EFL=63.5mm MgF2 400-700nm

The PAC043 is a high-quality achromatic doublet lens from MKS/Newport, designed for visible light applications within the 400-700nm spectrum. This lens, with a catalog number PAC043, is a multiplet lens, featuring a complex geometry that ensures superior optical performance.

The lens has a diameter of 25.4mm and a total thickness of 6.3mm at the edge. The inner and outer radii are 0, indicating a circular base shape. The effective focal length (EFL) of this lens is 63.5mm, making it suitable for a wide range of optical applications. The lens's front and back surfaces are coated with New MgF2BK7 from Figur, a high-performance coating that enhances its light transmission capabilities.

The lens is composed of two types of glass: N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, making the lens suitable for high-precision applications. The lens's geometry is intricate, with three radii (r, r1, and r2) and three thicknesses (thickness center 1, thickness center 2, and thickness center) specified. This geometry allows for precise control over the lens's optical properties.

The lens's coating and geometry are designed to minimize chromatic aberration, a common issue in optical systems. This makes the PAC043 an ideal choice for applications that require high color correction, such as microscopy, beam shaping, and laser applications.
