The 541-7205 is a Plano-Convex Lens, a type of spherical lens, sourced from EKSMA Optics. This lens has a diameter of 25.4 mm and a thickness of 2.5 mm at the edge. The effective focal length (EFL) of this lens is 50 mm, making it suitable for a variety of optical applications.
The lens is made from Barium Fluoride (BaF2), a material with a wide transmission range from UV to IR, making it ideal for use in ultraviolet (UV) and infrared (IR) optics. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens's geometry is defined by its inner and outer radii. In this case, the inner radius is 0 mm, and the outer radius is also 0 mm, indicating a plano-convex shape. The curvature of the convex side is defined by a radius of 25.615 mm.
This lens is designed to work with a wavelength of 3000 nm. It is important to note that the lens's performance can vary depending on the specific wavelength and the conditions of its use.
