KPC040AR.14 25.4 mm Dia. x -50 mm FL; AR coated; Plano-Concave Lens 430-700nm

This is a Plano-Concave Lens, type KPC040AR.14, sourced from MKS/Newport. The lens has a diameter of 25.4 mm and a focal length of -50 mm, making it suitable for a variety of optical applications. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range.

The lens features an Anti-Reflective (AR) coating on both the front and back surfaces. This AR coating, identified as AR-14, is designed to minimize reflection losses and improve transmission in the spectral range of 430-700 nm. The coating ensures high-quality performance and durability, making this lens an excellent choice for applications that require high transmission and low reflection, such as imaging systems, beam delivery systems, and laser applications.

The lens geometry includes a thickness of 5.17 mm at the edge and 2.5 mm at the center. The inner and outer radii are 0 mm, indicating a flat surface on one side and a curved surface on the other. The lens's base shape is circular, and its shape is spherical, which is common in optical systems due to its simplicity and ease of manufacturing.
