Micro Capillary

Glass for Optical Components

Glass, with excellent properties such as translucency, air tightness, and electrical insulation, is playing a very vital role in information technology fields. Various products based on our material development, precise processing, and assembly technologies are available.

Micro Capillary

Micro Capillaries are borosilicate glass capillaries with an inner diameter accuracy of ±0.5 microns. They are used for optical connectors, optical fiber splices and fiber supports in optical devices. Because Micro Capillaries have a polishing characteristic similar to silica optical glass fibers, the excellent polished face required for optical PC (physical contact) connection can be easily obtained by polishing. As a result, Micro Capillaries are suited for high-speed analog devices including CATV systems which require high return-loss properties. Micro Capillaries exhibit good elasticity that enhances the PC connection properties of the optical fiber. In addition, their high UV transmitting characteristic makes it possible to adhere capillaries and fibers, lenses or holders with UV-curable adhesive in a short time. Nozzle end type which allows firm insertion of the whole optical fibers with jackets and precision glass tube type which can be used as outer tube are also available.Product Information PDF
