Extended length recoater with automatic injection system


The AUTOCOATER 2 XL is designed for recoating applications where the protective acrylate coating is needs to be restored on long lengths of stripped fiber. It accommodates special silicone moulds that enable recoating of fiber sections up to 100 mm.

Like the standard length moulds, they are available in different sizes to cover a wide range of coating diameters. They can also easily be exchanged by the operator with no realignment of the system being required. The highly efficient UV LED curing system enables fast processing of both standard high index and specialized low index materials used in various high power applications. The customer selected recoating material is automatically injected from an easily attached 1 oz. Nalgene bottle, functioning as the recoater reservoir tank. This bottle as well as the entire injection system (including pump, supply lines and injection needle) may be removed and exchanged as a single unit.

This provides a convenient way to switch between different types of optical fibers and also makes the system easy to set up, optimize and rapidly reconfigure for different recoating applications and requirements. The AUTOCOATER 2 XL is therefore an ideal choice for fully automatic operator skill independent recoating of long strip lengths where flexibility is required to meet many different needs and specifications.

These features make the AUTOCOATER 2 XL ideal for production and research applications where long sections of stripped optical fiber of different diameters and with different coating materials need to be recoated in highly flexible way.

Program parameters are conveniently accessible through the built-in LCD touch screen control. The system can also be accessed via the USB port or Ethernet interface.
