The 111-1418E 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 200 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 3.1 mm and center thickness of 5 mm. The radii of curvature for the first and second surfaces are 189.6 mm and -189.6 mm, respectively. The lens is designed to work with a wavelength of 355 nm, typical of ultraviolet (UV) light sources.
The lens is made from UVFS MAL-1965, a material specifically designed for UV applications. This material ensures high transmittance and low absorption in the UV range, making it ideal for UV optical systems.
Please note that the lens is spherical, meaning it has a curved surface with a constant radius. This shape is common in optical lenses due to its simplicity and the ability to focus light to a point. However, it may introduce spherical aberration, a common optical distortion, in certain applications.
