KPC040AR.18 25.4 mm Dia. x -50 mm FL; IR coated; Plano-Concave Lens 1000-1550nm

The KPC040AR.18 is a Plano-Concave Lens, a type of spherical lens, sourced from MKS/Newport. This lens boasts a diameter of 25.4 mm and a focal length of -50 mm, making it ideal for applications that require a concave lens shape. The lens's geometry includes an edge thickness of 5.17 mm and a center thickness of 2.5 mm, contributing to its robust design.

The lens is constructed from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It has a wavelength of 589 nm, which is within the visible light spectrum. However, this lens is specifically designed for use in the infrared region, between 1000 nm and 1550 nm, making it suitable for various IR applications.

The KPC040AR.18 features a New AR-18 coating on both the front and back surfaces. This anti-reflective coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission. The coating is designed to operate within the lens's specified wavelength range, further optimizing its performance in IR applications.
