87-930 6mm Dia. x 24mm FL; Laser Grade Plano-Convex Lens Laser V-Coat 266nm
The 87-930 is a laser grade plano-convex lens, boasting a 6mm diameter and a 24mm focal length. This lens, sourced from Edmund Optics, is designed for use with a 266nm wavelength, making it suitable for various applications involving ultraviolet light.
The lens is made from fused silica, a material with a high damage threshold and excellent transmission properties in the UV range. The front and back surfaces of the lens are coated with Edmund Optics' Laser V-Coat 266, a proprietary coating that enhances the lens's performance in laser applications. This coating reduces reflection and increases transmission, thereby improving the efficiency and quality of the laser beam.
The lens's geometry is another notable feature. It has a thickness of 1.58mm at the edge and 2mm at the center, providing a robust structure while maintaining a low profile. The lens's effective focal length (EFL) is 24mm, and its back focal length (BFL) is 22.63mm. The lens's inner and outer radii are 0, indicating a plano-convex design, which is optimal for laser applications due to its low aberration and high efficiency.
