PAC090AR.14 50.8 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=400mm 430-700nm

The PAC090AR.14 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use in the visible light spectrum, with a effective focal length (EFL) of 400mm and a wavelength range of 430-700nm.

The lens features a primary diameter of 50.8mm, with a thickness at the edge of 11.1mm. The inner and outer radii are zero, indicating a circular shape. The EFL of 400mm is achieved through a careful design that includes two curved surfaces with radii of 199.9mm and -211.317mm, respectively.

The lens is constructed from two types of glass: N-BK7 and N-SF5, both from Schott. These materials were chosen for their excellent optical properties, which contribute to the lens's high performance. The lens is coated with a new AR-14 coating on both the front and back surfaces, which reduces reflective losses and improves transmission.

The lens is a multiplet, meaning it is composed of multiple elements. This design helps to correct chromatic aberration, a common issue in optical systems. The thickness at the center of the lens is 13mm, with individual thicknesses at the first and second centers being 8mm and 5mm, respectively.

According to the vendor's website, the PAC090AR.14 is currently in stock, making it readily available for immediate use. For more information, including pricing and availability, please refer to the vendor's website using the provided weblink.
