Micro Capillaries are borosilicate glass capillaries. They are used for optical connectors, optical fiber splices and fiber support in optical devices. Various kinds of shape and dimensions are available upon request.

Single round hole Capillary / Precision Glass Tube Round hole capillary for single or dual optical fibers. Precision glass tube is for outer tube. Square-hole Micro Capillary Two or four optical fibers can be aligned with one glass capillary. Dual-hole Micro Capillary Two optical fibers can be fixed at a certain distance precisely. Rectangular-hole Micro Capillary Several fibers can be aligned in a line.
