Hi My friends, i am Jing Chen, Optics Fiber and semiconductor is industry that i like, i believe this forum will influence a lot of optical engineer.
This is my first article about saphhire window.
Background:
Sapphire material has extremely stable physical and chemical properties, high strength, high temperature resistance, high humidity resistance, and corrosion resistance. It is widely used as the optical window of equipment or instruments. Engineers use brazing to fix the sapphire window on the metal bracket. To achieve airtightness of the product, however, due to the inconsistent thermal expansion coefficients of metal and sapphire, the sapphire window will be broken due to the different thermal expansion coefficients of the two during brazing.
Our innovation:
A>Metallized sapphire windows with Anti-Reflection coating or Bandpass coating inside.
B>In addition, we have a unique design. You can provide us with the metal bracket structure design drawings. Our engineers will review your bracket structure and design a brazing plan based on your bracket structure. After receiving your bracket, we will solder the sapphire window to your metal bracket and provide the sapphire window with Window, high airtight metal bracket for you, our technology can effectively solve the problem of sapphire window breakage during the soldering process, providing you with high reliability, convenient products.
