Three-Part Red Sapphire Watch Case for Watch Production Solutions
Synthetic sapphire, a material originally developed by Auguste Victor Louis Verneuil all the way back in 1902. However, in modern watchmaking sapphire can be used for much more than a just a watch’s crystal or the rubies in a movement, entire cases can be made out of it.
The main features of this method are:
1) In the process of crystal growth, it is convenient to observe the growth of crystals;
2) The crystal grows on the free liquid surface, is not forced by the crucible, can reduce the stress of the crystal;
3) It can be easily used to use the desired orientation seed crystal and "shrink neck" process, which helps to grow higher quality crystals at a relatively fast rate, and the crystal integrity is better;
4) The forced convection and natural convection interaction caused by the rotation of crystals and crucibles make the complex fluid flow action insurmountable and prone to crystal defects;
5) Mechanical disturbances tend to cause defects in the growth of large diameter crystals.
FATURES
1. High mechanical strength: the permeable infrared window material should have sufficient strength to withstand the high-speed movement of the speed pressure load;
2. Good thermal stability: the permeable infrared window material should be able to withstand the temperature shock caused by pneumatic heating and height changes, transmission ratio and refractive index should not change significantly with the change of temperature;
3. Good chemical stability: through infrared window material exposed to air, should be able to prevent the atmospheric salt solution or corrosion gas corrosion, and not easy to moisture;
4. High optical transmission rate, must be able to effectively transmit ultraviolet to medium infrared radiation;
5. Good optical characteristics, small optical scattering and good uniformity of refractive index;
Meets large window requirements.
