KBX040AR.16 12.7 mm Dia. x 75.6 mm FL; NIR coated; Double-Convex Lens NIR 650-1000nm

This KBX040AR.16 lens, sourced from MKS/Newport, is a high-quality optical component designed for use in the near-infrared (NIR) spectrum, specifically between 650 and 1000nm. It is a spherical lens, featuring a double-convex geometry, which is known for its ability to focus light effectively.

The lens has a diameter of 12.7mm and a center thickness of 3.521mm, with the edge thickness measuring at 3mm. The effective focal length (EFL) of this lens is 75.6mm, making it suitable for applications that require a longer focal length. The first and second radii of curvature are 77.538mm and -77.538mm respectively, contributing to its double-convex shape. The back focal length (BFL) is 74.43mm.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. It is coated with New AR-16, a coating specifically designed to reduce reflection in the NIR spectrum. This coating is applied to both the front and back surfaces of the lens.

Please note that the inner and outer radii are both 0, indicating that this lens does not have any special shaping or beveling on its edges. The lens is spherical in shape, which is a common and versatile geometry in optical systems.
