PAC17AR.15 25 mm Dia. N-FK5/N-F2 Achromatic Doublet; EFL=75mm UV-VIS 345-700nm
The PAC17AR.15 is a high-quality achromatic doublet lens from MKS/Newport, designed for use in the UV-VIS spectrum, specifically between 345 and 700nm. This lens, with a catalog number PAC17AR.15, is currently in stock and available for immediate purchase.
The lens features a circular geometry with a diameter of 25mm and a thickness at the edge of 5.4mm. The inner and outer radii are zero, indicating a symmetrical design. The effective focal length (EFL) of this lens is 75mm, making it suitable for a wide range of optical applications.
The PAC17AR.15 is composed of two types of glass, N-FK5 and N-F2, both from Schott. This combination helps to correct chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.
The lens is coated with New AR-15 on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases transmission, enhancing the overall performance of the lens.
The lens geometry includes a center thickness of 6.5mm for the first element and 2.5mm for the second, resulting in a total center thickness of 9mm. The first and second radii of curvature are -28.67mm and -76.58mm, respectively.
