This is the PAC075AR.14, a high-quality achromatic doublet lens from MKS/Newport, designed for use in the visible spectrum, specifically between 430 and 700nm. The lens is a multiplet, meaning it is composed of multiple elements, in this case, two, made from N-BK7 and N-SF5 Schott glass.
The lens has a diameter of 38.1mm and a total thickness of 6.1mm at the edge. The inner and outer radii are zero, indicating a circular shape. The effective focal length (EFL) is 150mm, and the curvature radii are r1=-68.69mm, r2=-208.07mm, and r=90.023mm. The lens has a central thickness of 9mm, with 7mm and 2mm at the center of each element.
The lens features New AR-14 coatings on both the front and back surfaces, optimized for high transmission and low reflection in the visible spectrum. This coating enhances the lens's performance, reducing losses due to reflection and increasing the overall light transmission.
The PAC075AR.14 is currently in stock and available for immediate purchase from the MKS/Newport website. With its high-quality materials, precise construction, and optimized coating, this lens is an excellent choice for a wide range of optical applications in the visible spectrum.
