APAC11 9 mm Dia. N-LAK8/N-SF57 Aspherical Achromatic Doublet; EFL=18mm 425-675nm
The APAC11 is a high-performance optical lens from MKS/Newport, designed for use in the 425-675nm wavelength range. This lens boasts a 9 mm diameter and features an effective focal length (EFL) of 18mm, making it suitable for a wide range of applications.
The lens is constructed as an achromatic doublet, comprising two different types of glass: N-LAK8 and N-SF57, both from Schott. This combination helps to minimize chromatic aberration, ensuring sharp and clear images. The lens also features aspherical surfaces, which further enhance its optical performance by reducing spherical aberration and distortion.
The APAC11 has a center thickness of 6mm, with the first and second centers measuring 4.5mm and 1.5mm respectively. The edge thickness is 5.16mm. The lens's geometry is circular, and it has an inner radius of 0mm and an outer radius of 0mm.
The lens is coated with New Vis-0 on both the front and back surfaces, enhancing its transmission and protecting it from environmental factors. This lens is a multiplet, meaning it is composed of multiple elements, and it is in stock, according to the vendor's website.
