LE1104-B 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=150mm 650-1050nm
The LE1104-B is a 25.4 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from the reputable vendor Thorlabs. This lens is specifically designed for use within the wavelength range of 650-1050nm, making it suitable for a variety of optical applications within this spectrum.
The lens features an effective focal length (EFL) of 150mm, which is a crucial specification for determining the lens's magnification power and field of view. The EFL is a measure of the distance from the lens's center to the point at which light rays converge or diverge, depending on the lens's design.
The LE1104-B is made from N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 2mm and a center thickness of 3.1mm.
The lens is coated with THo BBAR, a broadband anti-reflection coating that reduces reflection and increases transmission across a wide range of wavelengths. This coating is applied to both the front and back surfaces of the lens.
