Abstract
A method for making an optical collimating device having three or more ports. A test light having the same wavelength as that at which the filter is designed to operate is transmitted through the input collimator. The angle of incidence is measured, and the location where the reflected beam reaches the ferrule is determined. The data dictates where the output fiber pigtail should be positioned within the ferrule to achieve the measured angle of incidence for that transmitted wavelength and the spacing between input and output pigtails based on the angle of reflection. Multiple ferrules containing two or more pigtails corresponding to a particular filter operating at a particular wavelength are segregated into separate collimator bins that are marked accordingly.
