NYFORS MiniCoater 2

This compact and easy-to-use recoater is based on NYFORS' proven silicone mould technology which has been developed and refined in the course of the last twenty years. Moulds are available in different sizes to cover a range of coating diameters and can easily be exchanged by the operator with no realignment required. Custom moulds are available on request.

With the standard moulds the recoated part of the fiber is round with a cross section that perfectly and uniformly matches that of the original fiber coating, but moulds can also be selected for both overcoating and undersize recoating of optical fibers. These features makes the MiniCoater 2™ well suited for research and development operations and small scale production where the fiber type and dimensions need to be changed frequently.

Injection of the recoating compound is performed manually. While this does require a manual user operation, it also ensures flexibility because the user can immediately switch from one type of recoating compound to another (e.g. from a high-index recoating material to a low-index material) without any need to flush out a recoater reservoir and injection pumping system. This, in addition to the rapidly exchangeable mould sizes and shapes (for uniform diameter and undersize recoating as well as overcoating), ensures the flexibility and adaptability of the MiniCoater 2™.

Short curing times are achieved through a highly efficient UV LED array, which also has the ability to cure low-index recoating compounds used in fiber laser manufacturing. The MiniCoater 2™ has a simple two button control with a three digit display and comes in a small bench-top design.

The small size and light weight of the MiniCoater 2™ makes it ideal for situations where the recoater must be frequently moved from one lab or production area to another. The small size also facilitates easy ergonomic integration into a production work bench where space is at a premium. In addition, since the MiniCoater 2™ may be operated by battery power, and also due to the small size and weight, it is well suited to recoating in a remote field environment such as an oil drilling platform, or for other uses where a high degree of portability is required.
