Cylinders-rods & tubes

ARD-Optics manufactures polished cylinders-rods (stepped rods with very strict internal angle step) and tubes from sapphire and other optical materials.

Cylinders are used in medical installations as lightguides. Sapphire tubes are used in the lamps of high intensity, UV sterilization and etc.
