This Plano-Convex Lens, sourced from Laser Components, is a spherical lens with a diameter of 25.4 mm and a focal length of 2000 mm. The lens is uncoated, which means it does not have any anti-reflective or other coatings applied to its surface. The lens is made of fused silica, specifically the variant with the material ID "fused sil mal-1965".
The lens's geometry is defined by its diameter, thickness edge, and thickness center, all of which are 4 mm. The lens's inner and outer radii are both 0 mm, indicating that it is a plano-convex lens, meaning one side is flat while the other is curved. The lens's effective focal length (EFL) is 2000 mm, which is the distance from the lens at which a beam of light will converge to a point.
The lens is designed to operate at a wavelength of 248 nm. This specific lens is in stock and ready to ship.
