What is an N-BK7 Achromatic Lens?
An N-BK7 achromatic lens is a compound optical lens designed to reduce chromatic aberration and improve image quality. N-BK7 glass is widely used as an optical material because of its excellent optical homogeneity, transmission, and well-established processing characteristics.
How Does an Achromatic Lens Work?
An achromatic lens typically combines two optical elements with different dispersion characteristics. By balancing their optical properties, the lens can reduce color fringing and provide improved focusing performance over a selected wavelength range.
