This 69-590 optical lens, sourced from Edmund Optics, is a Plano-Convex Spherical Lens with a 6.0mm diameter and a 36.0mm focal length. The lens is designed for use with a wavelength of 1064nm and features a Laser V-Coat coating on both the front and back surfaces.
The lens's geometry includes a thickness of 1.36mm at the edge and 1.6mm at the center, with an Effective Focal Length (EFL) of 36mm. The Radius of Curvature (R1) is 18.61mm, and the Back Focal Length (BFL) is 34.95mm. The lens is made from N-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The Laser V-Coat coating on the lens is designed to enhance its performance in laser applications. This coating provides high transmission and low reflection, making it ideal for use in high-power laser systems.
The lens's base shape is circular, and its Sub Type is Spherical Lens. The item data indicates that the lens does not have any inner or outer radius, suggesting a simple, straightforward design that is easy to integrate into optical systems.
