APAC17 25 mm Dia. N-SK14/N-SF57 Aspherical Achromatic Doublet; EFL=40mm 425-675nm

The APAC17 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 effective focal length (EFL) of 40mm, making it suitable for a wide range of optical applications.

The lens is constructed as an achromatic doublet, comprising two different types of glass: N-SK14 and N-SF57. This configuration helps to minimize chromatic aberration, ensuring sharp and clear images. The doublet is aspherical, which means it has a non-spherical surface to further reduce optical aberrations and improve image quality.

The APAC17 has a thickness of 7.61mm at the edge and a center thickness of 11.5mm, with intermediate thicknesses of 9mm and 2.5mm at the centers. The lens's geometry is circular, with an inner radius of 0 and an outer radius of 0, providing a symmetrical optical path.

Both the front and back surfaces of the lens are coated with New Vis-0, a broadband anti-reflection coating designed to reduce surface reflections and improve transmission in the 425-675nm range.

This lens is currently in stock and available for immediate purchase through the MKS/Newport website. With its high-quality construction, advanced design, and broad wavelength compatibility, the APAC17 is an excellent choice for a wide range of optical systems and applications.
