The 87-618 is a Plano-Convex spherical lens, a type of optical component characterized by its single curved surface and a flat surface on opposite sides. This lens, sourced from Edmund Optics, has 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 infrared region, with a wavelength of 1064nm, making the lens ideal for use in laser applications.
The lens 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, reducing reflection and increasing transmission. The coating is applied using Edmund Optics' advanced V-coat technology, ensuring high-quality and durable performance.
The lens has a thickness of 1.4mm at the edge and 4.0mm at the center. The inner and outer radii are not specified, indicating that they are not a significant factor in the lens's performance.
