Golden Way's matched achromatic doublet pairs consist of two cemented achromatic doublets that are coated for use in the visible spectrum band(400-700nm). They are ideal for finite conjugate applications, such as image relay, NA conversion,or image magnification. In finite conjugate applications, both the object and image are a finite distance from the lens pair.
