38-477-INK 25.4mm Dia. x 150.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm

This product is a Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified as 38-477-INK, boasts a diameter of 25.4mm and a focal length of 150.0mm. The lens is designed with a plano-convex geometry, featuring a flat front surface and a curved back surface, which is common in many optical systems due to its simplicity and versatility.

The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including a high Abbe number and low dispersion. This makes it an ideal choice for applications that require high image quality and color correction.

The lens features a VIS-EXT coating on both the front and back surfaces. This coating, short for Visible Extended, is designed to enhance the lens's performance in the visible spectrum, specifically between 350-700nm. It provides improved transmission, reduced reflection, and increased durability, making it suitable for various applications, such as imaging, metrology, and beam manipulation.

The lens has a center thickness of 3mm and an edge thickness of 1.95mm, providing a robust structure while maintaining a sleek profile. The inner and outer radii are 0mm, indicating a sharp transition between the lens's surfaces. The back focal length (BFL) is 148.02mm, and the effective focal length (EFL) is 150mm, which are crucial specifications for designing and integrating the lens into optical systems.
