PAC055AR.14 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=125mm 430-700nm
The PAC055AR.14 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum, specifically between 430 and 700nm. This lens is a multiplet, meaning it is composed of multiple optical elements, in this case, two, to achieve superior optical performance.
The lens has a diameter of 25.4mm and an effective focal length (EFL) of 125mm. The doublet is constructed with N-BK7 and N-SF5 glass from Schott, two materials known for their excellent optical properties. The lens features a curvature of r=75.785mm, r1=-56.058mm, and r2=-167.954mm, providing a well-corrected image over a wide field of view.
The lens has a center thickness of 6.467mm, with individual center thicknesses of 4.3mm and 2.167mm for the first and second elements, respectively. The edge thickness is 4.9mm. The lens is coated with New AR-14 fromfigure on both the front and back surfaces, reducing reflective losses and improving transmission in the visible spectrum.
This lens is currently in stock and available for purchase on the MKS/Newport website. With its superior optical performance, robust construction, and wide spectral range, the PAC055AR.14 is an excellent choice for a wide range of optical applications.
