66-259 12.0mm Dia. x 18.0mm FL; Plano-Convex Lens Laser V-Coat 532nm
The 66-259 is a Plano-Convex Spherical Lens, a type of spherical lens with one side flat and the other side curved outwards. This lens, sourced from Edmund Optics, boasts a diameter of 12.0mm and a focal length of 18.0mm, making it suitable for a variety of optical 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 visible spectrum, as evidenced by the lens's specified wavelength of 532nm.
The 66-259 is equipped with a V-coat, a type of anti-reflective coating that is specifically designed for use with lasers. This coating, which is applied to both the front and back surfaces of the lens, helps to minimize losses due to reflection, thereby improving the efficiency of the optical system.
The lens has a thickness of 1.41mm at the edge and 3.0mm at the center. The inner radius is 0mm, while the outer radius is also 0mm. This suggests that the lens is designed to be used with collimated beams, as there is no curvature on the incident or exit faces.
