APAC16 25 mm Dia. N-LAK8/N-SF57 Aspherical Achromatic Doublet; EFL=35mm 425-675nm
The APAC16 is a high-performance lens from MKS/Newport, designed for use in the 425-675nm wavelength range. This lens boasts a 25 mm diameter and features an achromatic doublet design, combining N-LAK8 and N-SF57 Schott glass types. The achromatic doublet design helps to minimize chromatic aberration, ensuring sharp and clear imaging across the specified wavelength range.
The lens has an effective focal length (EFL) of 35mm, making it suitable for a variety of optical applications. The geometry of the lens includes a thickness of 7.9mm at the edge, with the inner and outer radii being 0, indicating a circular shape. The r value is 23.5, and the r1 value is -36.7, suggesting a complex aspherical design that can help to reduce spherical aberration and improve image quality.
The lens features a thickness of 9mm at the first center point and 2.5mm at the second center point, resulting in a total center thickness of 11.5mm. This design can help to reduce weight and improve the overall robustness of the lens.
The APAC16 lens comes with New Vis-0 coatings on both the front and back surfaces. These coatings can help to reduce surface reflections, improve transmission, and protect the lens surface from environmental contaminants.
