KBX040AR.18 12.7 mm Dia. x 75.6 mm FL; IR coated; Double-Convex Lens for IR 1000-1550nm
This is a high-quality Double-Convex Lens, sourced from the reputable vendor MKS/Newport. It is specifically designed for use in the infrared spectrum, with a wavelength of 589nm, and is suitable for use within the IR range of 1000-1550nm.
The lens has a base shape of a circle, with a diameter of 12.7mm. It features a double-convex geometry, with a thickness at the edge of 3mm and a center thickness of 3.521mm. The effective focal length (EFL) of this lens is 75.6mm, making it a versatile choice for a variety of 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 IR coatings on both the front and back surfaces. This AR-18 coating is specifically designed to reduce reflections and increase transmission in the infrared spectrum. The coating ensures that the lens performs optimally within its specified wavelength range, minimizing losses due to reflection.
