34-139 25mm Dia. x 38mm FL Fused Silica Plano-Convex Lens Laser V-Coat 1064nm
This 34-139 optical lens, sourced from Edmund Optics, is a 25mm diameter by 38mm focal length Plano-Convex lens, designed for use with a 1064nm wavelength. The lens is made from fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.
The lens features a spherical shape, with a 17.42mm radius of curvature on the convex side. The edge thickness measures 1.96mm, while the center thickness is 7.25mm, providing a robust and durable structure. The lens has a high refractive index, leading to a short back focal length of 33.03mm, which can be beneficial in certain optical system designs.
Both the front and back surfaces of the lens are coated with Edmund Optics' Laser V-Coat 1064, a proprietary coating designed to enhance the lens' performance in laser applications. This coating provides high transmission and low reflectivity at the specified wavelength, ensuring optimal light transmission and reducing unwanted reflections.
