This 12mm diameter, 36mm focal length laser grade plano-convex lens, model 67-941, is a high-quality optical component designed for use with 266nm wavelength lasers. Sourced from the reputable vendor Edmund Optics, this lens boasts a laser-grade quality, ensuring optimal performance and reliability in demanding applications.
The lens features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). This design allows for efficient light collimation and focusing, making it suitable for a wide range of laser applications. The lens has a diameter of 12mm and a thickness of 1.37mm at the edge, increasing to 2.5mm at the center, providing robustness and durability.
The lens's material is fused silica (mal-1965), a low-autofluorescence material that is highly transparent across the UV spectrum. This makes it ideal for use in UV laser systems, where high transparency and low autofluorescence are crucial.
The lens is coated with Edmund Optics' Laser V-Coat 266, a specialized coating designed for use with 266nm lasers. This coating enhances the lens's performance by reducing surface reflections, improving transmission, and increasing laser damage threshold.
