Optical filter device having molded, single-index collimating lens |
摘要 |
An optical filter device (100) for collimating input signals and selecting optical signals in a predetermined wavelength band includes a dual fiber pigtail (DFP) (112) receiving an input and output optical fibers (113, 114), a molded lens (111), a sleeve (130) and a filter (120). The molded lens between the DFP and the filter has a single index and collimates the dispersed light beams coming from the input optical fiber to parallel-light beams, and converges the parallel light beams reflected by the filter for transmission into the output optical fiber. The filter absorbs optical light beams in predetermined wavelength bands. The sleeve allows connection of the filter to the lens without requiring use of epoxy on optically functional parts of the molded lens.
