PAC075 38.1 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=150mm MgF2 400-700nm

The PAC075 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use in the visible spectrum, with a recommended wavelength range of 400-700nm. The lens is characterized by its 38.1 mm diameter and a focal length of 150mm, making it suitable for a wide range of optical applications.

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, including low dispersion and high transmission in the visible spectrum. The lens features a complex geometry, with a center thickness of 9mm, an inner radius of 0mm, and an outer radius of 0mm. The edges of the lens are thicker, with a thickness of 6.1mm, providing additional structural integrity.

The PAC075 is coated with a broadband anti-reflection coating, specifically MgF2, which is applied to both the front and back surfaces of the lens. This coating reduces surface reflections, thereby increasing the overall transmission of the lens and minimizing unwanted ghosting and flaring effects.

In terms of shape, the PAC075 is a multiplet lens, meaning it is composed of multiple individual lens elements. This design allows for the correction of various optical aberrations, resulting in a lens with high resolution and excellent image quality.
