111-1422E 38.1 mm Dia. x 250 mm FL; Uncoated; Double-Convex Lens
The 111-1422E is a double-convex lens, also known as a biconvex lens, sourced from EKSMA Optics. This lens boasts a diameter of 38.1 mm and a focal length of 250 mm, making it suitable for a wide range of optical applications. The lens is uncoated, which means it does not have any additional layers to protect it or modify its optical properties.
The lens's geometry is characterized by its edge thickness of 2.5 mm and center thickness of 4 mm. The radii of curvature for the first and second surfaces are 237.4 mm and -237.4 mm, respectively. The lens's inner and outer radii are both 0, indicating that the lens is uniformly curved from edge to edge.
The lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet spectrum at a wavelength of 355 nm. This makes the lens particularly suitable for applications in UV optics.
Please note that the lens is spherical in shape, meaning it has a smoothly curved surface. This shape is common in optical lenses due to its simplicity and the ease with which it can be manufactured. However, it may introduce spherical aberration in some applications, which is a type of optical distortion.
