TO Caps & Lenses
In general, one can distinguish between two different types of TO caps:
Molded TO Caps & Lenses
Metal and glass are fused without the use of any other material. These TO caps are suitable for all conventional types of optical signal transmission. Read more >
Soldered TO Caps & Lenses
Metal and glass are fused with the aid of a solder glass. These TO cap are suitable for precision applications with special optical components. Read more >
The headers and caps are welded together to form a TO housing. During this process, the oxygen inside the encapsulated spaces is removed to increase protection against corrosion. Please refer to our Technology section for more information about this process.
Both types of caps can be manufactured for all standard TO designs. The following table lists some of the most common designs and their associated header designs:
