LE1104 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=150mm Uncoated
The LE1104 is a spherical lens with a base shape of a circle, designed and manufactured by Thorlabs. This lens is a positive meniscus type, meaning it has a convex-concave shape. The lens has a diameter of 25.4 mm and a thickness at the edge of 2 mm, while the center thickness is 3.1 mm. The effective focal length (EFL) of this lens is 150 mm, making it suitable for a variety of optical applications.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The inner and outer radii of the lens are not specified, indicating that they may be customizable based on specific application requirements.
The LE1104 operates at a wavelength of 587.6 nm. It does not come with any coating, which means it is uncoated. However, coatings can be added based on specific application needs to enhance the lens's performance.
