Abstract
The invention includes a ferrule having a layer of material on an inner surface of a hole therein which is selected to be preferentially softenable relative to the bulk material of the ferrule. The ferrule according to the present invention can be fused to optical fibers, capillaries and the like while reducing deformation of the fused component and the ferrule. A fiber Bragg grating device and a flow cell device are also provided.
Claims11
A flowcell device comprising:
- a ferrule having an interior wall defining a hole, at least a portion of the interior wall comprising a layer of material preferentially softenable relative to the remainder of the ferrule;
- and
- at least one capillary tube extending into the hole and partially fused therein by at least partially softening the layer;
- wherein the ferrule and the layer of material preferentially softenable relative to the remainder of the ferrule are substantially similar materials.
