UV curing in an Inert Atmosphere
This video shows MY Polymers low refractive index coating OF-133, being cured inside a Nitrogen chamber on an optical fiber drawing tower. The fiber, that was just coated by the OF-133 is entering the UV curing section. UV curing is done in such inert conditions to minimize Oxygen competition. -
How to coat
This video shows how to produce an even, thickness controlled coating, using simple means -
Low Refractive Index Demo
This video demonstrates the MY-133-V2000 index of 1.33, which is identical to water. The fish was produced by UV curing inside a transparent mold with small grooves, to create opacity that enhances the optical effect.

RECOATING MATERIALS |
|
Our recoating materials are used intensively in the construction of fiber lasers. Splices which are created during the fiber laser assembly process, have to be recoated. Likewise, each component used in the assembly of a fiber laser has to be recoated and encapsulated by a recoating material.
Currently, the most common optical fibers (both active and passive) use primary coatings with an index of 1.36 (e.g. OF-136), recoating materials with the same index 1.36 are very common in recoating applications. Typically, 1.36 index materials are used for recoating splices, Pump Power Combiners, Couplers, and FBG (Fiber Bragg Gratings).
The following drawing shows the various applications for our recoating materials. |
