PAC052AR.14 25.4 mm Dia. N-BK7/N-SF5 Visible Achromatic Doublet; EFL=100mm 430-700nm

The PAC052AR.14 is a high-quality achromatic doublet lens, designed and manufactured by MKS/Newport. This lens is specifically engineered for use in the visible light spectrum, spanning from 430 to 700 nanometers. The lens boasts a 25.4 millimeter diameter, 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 are carefully selected to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points. By using an achromatic doublet design, the PAC052AR.14 effectively corrects this aberration, ensuring sharp, clear images across the entire visible light spectrum.

The lens has an effective focal length (EFL) of 100 millimeters, providing a moderate level of magnification. The EFL, combined with the lens's diameter, gives the lens a relatively long focal ratio, which can be beneficial in applications where a narrower field of view is desired.

The PAC052AR.14 is coated with a new AR-14 coating on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections, improving light transmission and enhancing the overall performance of the lens.

In terms of geometry, the lens has a thickness of 5.2 millimeters at the edge, with the center thickness varying between 5 millimeters and 2.17 millimeters for the two individual lens elements. The lens also features a curvature radius of 60.741 millimeters for the first surface, -44.71 millimeters for the second surface, and -133.104 millimeters for the third surface.

According to the vendor's website, the PAC052AR.14 is currently in stock, making it readily available for immediate use in your optical systems.
