Custom Sapphire Tubes, Semi-Polished, made from Al₂O₃ Single Crystal for Optical Instruments.
Sapphire semi-polished tubes are manufactured from optical-grade sapphire (α-Al₂O₃ single crystal). They undergo a specific polishing process that results in a surface finish quality positioned between rough-machined blanks and fully polished, mirror-finish tubes. The "semi-polished" designation indicates that the tubes have been processed to remove the majority of machining marks, achieving a uniform surface smoothness suitable for applications where a high-gloss finish is not mandatory, offering a cost-effective solution without compromising on core material properties.
The defining characteristics of these tubes derive from the intrinsic properties of sapphire and the specific semi-polished condition:
Utilizing this combination of properties, sapphire semi-polished tubes are employed in various high-tech sectors:
The table below outlines key technical parameters.
Note: Specifications for "semi-polished" tubes generally fall between the ranges for standard and high-precision tubes.
