About This Product
■We handle over 300 items of glass bulbs including over 100 types including optical micro ball lenses, soda glass, sapphire, and ceramics.
Ball lenses are available in diameters starting from 0.13mm and can be manufactured to the international standard AFBMA Grade 3. It is used in large quantities as microball lenses in the optical communications field.
We make micro ball lenses from materials and then directly coat them (AR coating, etc.). We carry over 70 types of optical glass balls. The coating uses PVD (physical vapor deposition) and CVD (chemical vapor deposition). The mainstream wavelength bands currently used in communications are 830-850nm, 850nm-1,300nm, 1,270nm-1,310nm, and 1,500nm-1,600nm. Ceramic has excellent strength and hardness.
■What is soda glass?
Also known as ``Soda-Lime-Glass,'' this glass is commonly used for window glass. Soda glass contains silica sand (SiO2), sodium carbonate (Na2CO3), and calcium carbonate (CaCO3) in a ratio of approximately 7:2:1. It is easy to process due to its low melting point, but it is sensitive to rapid heating and cooling and has low chemical durability. Because the raw materials are relatively easy to obtain, the ones that are cheap and have thick edges are difficult to break and make a dull sound when tapped.
■Standards
・Softening temperature: 720-730℃
・Specific gravity: 2.5g/cm3
■Characteristics of soda glass ball (sphere)
1. Resistant to heat.
2. Harder than lead glass and scratch resistant.
3. Transparency is low.
4. It makes a dull sound when I play it.
5. Resistant to chemicals and does not rust.
6. Easy to color and has excellent processability and moldability.
7. It has excellent properties such as light, electricity, and magnetism.
8. It is produced in large quantities, so it is cheap and has good homogeneity.
■General uses of soda glass
Widely used for physics and chemistry, medical instrument valves, plastic bearings, flow meter windows and bottles, tableware glass, glassware, etc.
