HO-BXL25-20C 25mm Dia. N-BK7 Double-Convex Lens; EFL=500mm Single Layer MgF2

This HO-BXL25-20C lens is a high-quality optical component manufactured by Holmarc Opto-Mechatronics. It is a double-convex spherical lens, characterized by its circular base shape and a diameter of 25mm. The lens has a thickness of 2mm at the edge, making it robust and suitable for various applications.

The lens has an effective focal length (EFL) of 500mm, which is a critical parameter in lens selection. It determines the lens's magnification power and is inversely proportional to the angle of view. The EFL of this lens suggests that it is designed for long-distance focusing and high-magnification applications.

The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. It has a high refractive index and low dispersion, making it ideal for a wide range of applications, from imaging to laser systems.

The lens features a single layer of MgF2 coating on both the front and back surfaces. This coating reduces reflection and increases transmission, enhancing the lens's performance in various applications. The coating is applied at 0 degrees angle of incidence (AOI), ensuring uniform coverage and optimal performance.
