Synthetic sapphire single crystal (Al2O3), the hardness is second only to Diamond. At the same time, it has ultra-wide transmittance performance from ultraviolet to infrared. It can be made into precision balls for use in mechanical and optical systems. The precision sapphire balls can be used as coupling for optical communication or as precision valve cores.
Vanrun OE provides sapphire balls of the following specifications:
- Size: 2mm to 10mm
- Size tolerance: +/-5 micron
- Ellipticity: less than 5 micron
- Surface quality: 40-20
Cut or grind into a hemisphere with a precise sapphire ball. The planar surface is then polished with optical standards. This is the precise sapphire hemispheric lens. They are widely used in LED lighting, optical communications, laser medical devices and many other fields.
Vanrun OE provides sapphire half-balls of the following specifications:
- Ball Size: 2mm to 10mm, based on sapphire ball standard
- Ball Size tolerance: +/-5 micron
- Ellipticity: less than 5 micron
- Thickness: half the diameter of the ball or customized
- Surface quality: 40-20
- Chamfer: sharp edge
The standard sapphire is machined into a cylindrical ground surface, with both ends of the original polished spherical surface preserved. This is the sapphire drum lens. It's also like a rod lens with two ends spherical.
Vanrun OE provides sapphire drum lenses of the following specifications:
- Ball Size: 2mm to 10mm, based on sapphire ball standard
- Ball Size tolerance: +/-5 micron
- Ellipticity: less than 5 micron
- Drum diameter: 90% of the diameter of the ball or customized
- Drum diameter tolerance: +/-0.05mm
- Surface quality: 40-20
- Chamfer: sharp edge
