The 34-108 5mm Dia. x 20mm FL UV Plano-Convex Lens is a high-quality optical component designed for use with laser systems operating at a wavelength of 633nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is of the Spherical type, specifically a Plano-Convex design, which features a flat front surface and a curved back surface. This design is ideal for applications that require a collimated beam, such as laser machining or material processing. The lens has a base shape of Circular, with a diameter of 5mm, and a thickness of 1.5mm at both the edge and the center.
The Effective Focal Length (EFL) of this lens is 20mm, which is the distance from the lens's principal point to the point at which the beam converges or diverges. The lens's front and back surfaces are coated with Edmund Optics' Laser V-Coat 633, a proprietary coating designed to enhance laser damage threshold and transmission at the specified wavelength.
The lens is made from Fused Silica (Mal-1965), a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature across the lens surface.
