PAC034 12.7 mm Dia. N-BAK4/N-SF10 Visible Achromatic Doublet; EFL=76.2mm MgF2 400-700nm
The PAC034 is a high-quality optical lens from MKS/Newport, designed for visible light applications within the 400-700nm spectrum. This achromatic doublet lens, with a diameter of 12.7 mm, is a multiplet type, featuring a complex geometry that ensures superior optical performance.
The lens's geometry includes an effective focal length (EFL) of 76.2mm, a thickness at the edge of 4.4mm, and a center thickness of 5mm, which is distributed between two centers with thicknesses of 3.5mm and 1.5mm respectively. The lens's inner and outer radii are 0mm, and it has a curvature radius of 48.834mm for the first surface and -37.152mm and -123.853mm for the second and third surfaces respectively.
The PAC034 is composed of two types of materials: N-BAK4 from Schott and N-SF10 from Schott. These materials are known for their excellent optical properties, making them ideal for use in achromatic doublets. The lens is coated with MgF2 on both the front and back surfaces, which enhances its transmission capabilities within the specified wavelength range.
