The KPC067AR.18 is a Plano-Concave Lens, a type of spherical lens, with a diameter of 50.8 mm and a focal length of -250 mm. This lens is sourced from MKS/Newport, a renowned vendor in the optical industry. The lens is designed for use within the infrared spectrum, specifically between 1000-1550nm, making it suitable for applications such as IR spectroscopy, thermal imaging, and other infrared-based technologies.
The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens features a new AR-18 coating on both the front and back surfaces, which is designed to reduce reflection and increase transmission within the specified wavelength range. This coating enhances the lens' performance in IR applications by minimizing signal loss and improving image quality.
The geometry of the lens includes a thickness of 4.54mm at the edge and 2.5mm at the center. The lens' inner and outer radii are both 0, indicating a plano surface on one side and a concave surface on the other. The back focal length (BFL) is -251.64mm, slightly longer than the specified focal length due to the lens' concave design.
