This laser grade plano-convex lens, sourced from Edmund Optics, boasts a diameter of 25.4mm and a focal length of 35mm, specifically designed for use with a wavelength of 266nm. The lens is crafted from UVFS MAL-1965, a material well-suited for applications in this spectral range.
The lens geometry is characterized by a thickness of 3.04mm at the edge, increasing to 9.53mm at the center, and an effective focal length (EFL) of 35mm. The front surface of the lens features a plano-convex shape with a radius of curvature of 16.66mm, while the back surface is planar. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
The lens is coated with Edmund Optics' Laser V-Coat 266nm on both the front and back surfaces. This coating enhances the lens's performance in laser applications, providing improved durability and resistance to environmental factors.
