Abstract
This invention discloses a dual fiber optical component that includes a first holding tube for containing and holding a dual fiber capillary and a collimator lens. The dual fiber capillary has first optical fiber and a second optical fiber with the first optical fiber transmits an input light beam for projecting through the collimator lens as a collimated beam. The dual fiber component further includes a second holding tube containing and holding an optical filter for receiving the collimated beam from the collimator lens. The filter further projecting a portion of the collimated beam back through the collimator lens for transmitting to the second optical fiber of the dual fiber capillary. The first holding tube has a first interface tube end forming with a convex spherical profile and the second holding tube has a second interface tube end forming with a concave spherical profile corresponding to the convex spherical profile of the first interface tube end.
