APAC14 12.5 mm Dia. N-LAK8/N-SF57 Aspherical Achromatic Doublet; EFL=25mm 425-675nm
The APAC14 is a high-performance optical lens from MKS/Newport, designed for use in the 425-675nm wavelength range. This lens boasts an effective focal length (EFL) of 25mm and a circular base shape with a 12.5mm diameter.
The lens is constructed as an achromatic doublet, featuring two different types of glass - N-LAK8 and N-SF57, both from Schott. This configuration helps to minimize chromatic aberration, ensuring sharp and clear images. The lens also incorporates aspherical surfaces, which further enhances its optical performance by reducing spherical aberration.
The APAC14 has a center thickness of 5.5mm, with the first and second centers measuring 4mm and 1.5mm respectively. The edge thickness is 4.32mm. The inner and outer radii are both zero, indicating a symmetrical design.
The lens is coated with New Vis-0 on both the front and back surfaces, which provides excellent anti-reflection properties, further enhancing its performance in various applications.
