PAC087 50.8 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=200mm MgF2 400-700nm
The PAC087 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for visible light applications, with a wavelength range of 400-700nm. The lens boasts a diameter of 50.8mm and a focal length of 200mm, making it a versatile choice for a wide range of optical systems.
The lens is constructed from two types of glass: N-BK7 and N-SF5, both from Schott. These materials are chosen for their excellent optical properties, including low dispersion and high transmission in the visible spectrum. The lens is coated with MgF2, which further enhances its performance by reducing surface reflections and improving transmission.
The PAC087 features a complex geometry, with a range of radii and thicknesses designed to minimize optical aberrations. The edge thickness is 8.1mm, while the center thickness is 12mm. The lens's inner and outer radii are 0mm, and it has a front and back coating of new mgf2bk7fromfigur.
This lens is available for purchase directly from the MKS/Newport website, where it is listed as in stock. The catalog number for this lens is PAC087, and it can be found at the following link: https://www.newport.com/p/PAC087.
