87-598 15.0mm Dia. x 18.0mm FL; Plano-Convex Lens Laser V-Coat 405nm

The 87-598 is a Plano-Convex spherical lens, a type of optical component characterized by its single curved surface and a flat surface on the opposite side. This lens, sourced from Edmund Optics, boasts a diameter of 15.0mm and a focal length of 18.0mm, making it suitable for a wide range of applications.

The lens is made from n-SF5 Schott, a high-quality optical glass known for its excellent transmission properties and chemical resistance. This material is particularly suitable for use in the ultraviolet region of the spectrum, as evidenced by the lens's specified wavelength of 405nm.

The 87-598 features a laser V-coat coating on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in laser applications, providing improved damage threshold and laser-induced damage. The coating also offers high reflectivity at the specified wavelength, further enhancing the lens's suitability for laser use.

The lens has a thickness of 1.4mm at the edge and 4.0mm at the center, providing a robust and durable construction. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface.
