KBX052AR.18 25.4 mm Dia. x 50.2 mm FL; IR coated; Double-Convex Lens IR 1000-1550nm

This is a high-quality Double-Convex Lens, sourced from the reputable vendor MKS/Newport. It is specifically designed for use within the infrared spectrum, with a wavelength of 589nm, and is suitable for applications within the 1000-1550nm range.

The lens has a base shape of a circle, with a diameter of 25.4mm. It features a thickness at the edge of 3mm and a thickness at the center of 6.226mm. The effective focal length (EFL) of the lens is 50.2mm, making it ideal for a variety of optical applications.

The lens is made from the high-quality material n-BK7 Schott, a borosilicate glass known for its excellent optical properties. This includes a low coefficient of thermal expansion, making it resistant to thermal shock, and a high Abbe number, which reduces chromatic aberration.

The lens features a new AR-18 coating on both the front and back surfaces. This anti-reflective coating enhances the lens' performance by reducing surface reflections, thereby increasing transmission. The coating is specifically designed for use within the infrared spectrum, making it ideal for this lens.

The lens' geometry is spherical, with an inner radius of 0mm and an outer radius of 0mm. The back focal length (BFL) is 48.1mm.
