PAC037AR.14 12.7 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=88.9mm 430-700nm

Discover the PAC037AR.14, a high-performance 12.7 mm diameter achromatic doublet lens, specifically designed for visible light applications within the 430-700nm spectrum. This lens, offered by MKS/Newport, boasts an effective focal length (EFL) of 88.9mm, making it suitable for a wide range of optical systems.

The lens features a multilayer anti-reflection (AR) coating on both the front and back surfaces, denoted as "new ar-14 fromfigure". This advanced coating significantly reduces surface reflections, thereby enhancing overall transmission and minimizing ghosting and flare effects.

The PAC037AR.14 is a multiplet lens, composed of two distinct materials. The first material is N-BK7, a high-quality borosilicate crown glass, while the second is N-SF5, a dense fluorite crown glass. These materials have been carefully selected to achieve superior achromatic performance, minimizing chromatic aberrations across the visible spectrum.

The lens geometry includes a central thickness of 4.5mm, with 3mm and 1.5mm thicknesses at the first and second centers, respectively. The lens has a curved shape, with radii of 54.097mm, -39.663mm, and -117.483mm for the first, second, and outer surfaces, respectively. The lens is designed to be edge-thick, with a thickness of 4mm at the edge.
