Chapter 4 Device Selection
When purchasing a PTR306 or PTR306B, it is necessary to select a mold assembly and fiber holding block inserts
that best match the desired coating diameters of your fiber.
Automatic and Remote Manual Injection System
The PTR306 and PTR306B are both manual fiber Recoaters with an integrated linear Proof Tester, the major
difference comes in the type of injection system utilized by the device. The PTR306 comes with the automatic recoat
injection pump fitted inside the unit. This pump system can be activated either by the “Inject” button on top of the
unit, or with the Handset Controller. An automatic injection system will inject a predetermined volume of recoat
material into the mold assembly. It is compatible with high-index recoat material only.
The PTR306B comes with a manual injection system. This pump system provides a method of manually dispensing
recoat material directly from the recoat bottle into the injection port. This system consists of a syringe with a knurled
dispensing screw, which is fitted to a distribution valve with a two-position selection lever. It is compatible with both
high- and low-index recoat material.
Mold Assemblies
The Mold Assemblies are composed of split quartz mold plates which,
when closed, form the cylindrical mold cavity around the exposed
section of the fiber being recoated. When purchasing the Recoater for
the first time, it is necessary to choose a mold assembly that is
appropriate for the desired fiber coating diameter. They are available for
Ø280 µm, Ø430 µm, or Ø600 µm fiber coatings. Custom mold sizes up
to Ø900 µm are available; please contact Thorlabs for more information. Additional mold assemblies may also be
purchased and swapped out by the user. The assembly simply screws to the top of the device, making the removal
and install simple and easy.
Inserts for Fiber Holding Blocks
When purchasing a PTR306 or PTR306B, the proper set of inserts need to be selected. A total of four inserts (two
top and two bottom) are required for a full unit. The inserts are seated in and secured to the fiber holding blocks.
They can easily be swapped out for different sizes, allowing our Recoaters to adapt quickly should different fiber
coating sizes be desired. The VHJ Series inserts (designed for Recoaters with linear Proof Testers) are compatible
with fiber coating sizes ranging from Ø80 µm to Ø1000 µm.
