A mirror is an optical element that uses reflection. Mirrors can be divided into flat mirrors, spherical mirrors and aspheric mirrors according to their shapes. Products are widely used in optical equipment, teaching, industrial lenses, camera, video shooting, automation, medical, measuring and surveying equipment, aviation, astronomy, etc.. So it requires different materials for different work range.Our products cover ultraviolet, visible light and infrared band. The diameter scope of processing is around Φ1 for endoscopic lens~Φ300mm for standard spherical lenses and windows,etc.
Tianjin Tengteng Optoelectronic Technology Co., Ltd. can provide different coating according to customers' need, such as Protected Aluminum, Enhanced Aluminum, Protected Silver, Protected Gold, or Dielectric and so on.

1.To ensure safe shipment, our glass will be taken good care of by this way.

2. Paper and Cork liner will be put between every two glass to prevent them hurt each other.

3. Glass will be put in suitable wooden crate with Corner Protectors.

4. Under wooden crate there will be legs for forklift easy loading and unloading.

Q1: How to judge the quality of float glass?
A1: Flatness, transparency, colorless, impurities, bubbles, etc.
Q2: How to reduce the self-implosion?
A2: The high quality float method is used for hot dip treatment, edge treatment and proper stress intensity. Pay attention to avoid side collision of glass during installation.
Q3: Scope of use of toughened glass?
A3: Safety is not involved in some parts of the building, but it is necessary to install toughened glass to improve the compressive strength and explosion-proof capacity,not to endanger the person safety
Q4: When toughened glass is broken, is the grain smaller the better?
A4: No, the smaller the particle, the easier it is to explode.
Q5: Can toughened glass and semi-toughened glass be made into laminated glass?
A5: Can't. The national standard stipulates: the glass that stresses the difference cannot make laminated glass, because in use process, the pressure that two pieces of glass bears is different.
Q6: Whether the laminated glass can fire, can the sound insulation?
A6: No, the smaller the particle, the easier it is to explode.
Q7: How many uv low-e glass can reduce?
A7: It is not fireproof glass, but has certain fireproof ability, also can soundproof, laminated glass is inside whole sound wave frequency range, in control noise is very good.
Q8: Does the air in the insulating glass do not oxidize the membrane?
A8: No, because there is a molecular sieve in the insulating glass, and the molecular sieve always keeps the air dry, so the membrane is not oxidized.
Q9: How much ultraviolet radiation can low-e glass reduce?
A9: It can reduce uv by 14% compared to heat reflecting glass. That's a 25 percent reduction in uv radiation compared to white glass.
