摘要
The invention teaches the design and assembly configurations for a free space DWDM device. Particularly, when using the free space DWDM devices for channel spacing less than 200 GHz, a small angle of incidence requires a longer optical path and adjustments must be made by folding the optical path or using double layers of optical components such as collimators to shorten the device and obtain the compact dimensions of the DWDM device. The design of the compact optical devices are implemented and assembled with various positioning and mounting methods for the newly designed optical base member, collimators, and filters to obtain the desired compact free space DWDM devices
