Abstract:
1. A method for fabricating an optical device having at least a first and a second optical component group using an athermal platform comprising: aligning and adjusting a relative position between two optical component groups using a position-holding-and-fixing means, where a first component group includes one or more optical components positioned substantially within a first extension tube, the one or more optical components being coupled to an interior surface of the first extension tube, and securely fixing the two optical component groups within the position-holding-and-fixing means including fixing the first component group within a second extension tube as a first building block, where aligning the relative position between two optical component groups using the position holding-and-fixing means includes aligning a dihedral angle between the two optical component groups including rotating at least one of the optical component groups relative to the other optical component group.
