Optical Fiber Recoater
FSR115/116/117/115L
FSR115, FSR116, FSR117 and FSR115L provide automatic operation with various sizes of quartz molds available. Colored and non-colored fibers can be recoated. This new recoater series introduces easily exchangeable molds, resin bottle and pump assemblies. The new bubble removal system eliminates bubbles before they reach the mold cavity. A programmable resin injection system provides an exact volume of resin to the mold cavity to ensure consistent recoat performance.

Features
Faster
Shortened UV curing resin injection time
New designed pump provides shorter UV resin injection time. It also provides 25% shorter total recoating time than previous model.
How to recoat
*1: Test condition:
(1) UV recoat Resin：Japan Fine Coatings Co., Ltd. 950Y200 or Luvantix ADM Ltd. PC-373LD
(2) Recoat diameter：280µm
(3) Recoat Length：20mm
(4) Fiber：Clad Diameter 125µm/Transparent UV 250µm Coating Diameter, Coating Stripping length 16mm
(5) Environmental Condition： 25℃
More accurate
Improved recoating length repeatability
The recoat mold has slight steps on the U-groove to provide an air vent. It helps to improve the recoating length repeatability, as well as the ability to reach a max. 50mm length.
*2: The table does not guarantee the recoat length accuracy.
Test condition:
(1) UV recoat Resin：Japan Fine Coatings Co., Ltd. 950Y200
(2) Recoat diameter：280µm
(3) Recoat Length：10-50mm
(4) Fiber：Clad Diameter 125µm/Transparent UV 250µm Coating Diameter, Coating Stripping length 60mm
(5) Environmental Condition： 25℃
(6) Model : Excepting FSR115L
More user friendly
Fiber and recoating centering adjustment is now possible by the user
The Fiber height adjuster enables the adjustment of fiber diameter centering by setting the fiber to be centered in the mold.
The spacers allow for fine tuning based on original fiber coating variations.
Clear observation of resin injection
LEDs under the mold shows the injected resin more clearly.

Recoat mode suggestion function
The new molds are equipped with RFID tags on the bottom of the mold. The FSR115 series scan the RFID and suggest suitable programs according to the RFID data. This improves our customers efficiency when changing molds.
