These replacement items are provided for customers with previous-generation PTR303(B), PTR304(B), PTR306(B), and PTR307(B) units.
New customers are encouraged to consider one of our fiber recoaters with UV curing LEDs. Upgrades to UV LEDs may be available for owners of previous-generation units; please contact Tech Support for more information.
Our mold assemblies are available in a variety of sizes so that customers can choose the right mold coating diameter for their application. Custom mold coating sizes are available up to Ø900 µm. Please contact Tech Support for more information on custom molds.
Inserts for Fiber Holding Blocks
We offer a variety of fiber holding block inserts in order to support a wide range of fiber coating diameters. The inserts cover fiber coatings from Ø80 µm to Ø1000 µm; a total of four are necessary for each recoater, two top inserts and two bottom inserts.
Thorlabs offers both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials. Previous-generation recoaters with manual injection pumps (Item #s PTR303B, PTR304B, PTR306B, and PTR307B) are compatible with both types of recoat material. Manual recoaters with an automatic injection system (Item #s PTR303, PTR304, PTR306, and PTR307) are compatible with the high-index recoat material, but they may be customized to work with both the low- and high-index recoat material. Please contact Tech Support for more information.

1.Do you provide any test report for recoater unit? [eg., by including results of two recoatings of a fiber (one HI and one LI acrylate) such as adhesion, tension etc., If not what else (certificate of compliance etc.,) do you provide confirming quality of the product 2.For manual recoat injector ( PTR 303B), how can user programme inject rate, inject amount? These parameters are controlled by manual operation of injector eg., by pressure applied (manually) on syringe piston. 3. Do you provide installation service in India? If so what is additional cost of installation/demonstration?

- Compatible with Previous-Generation UV Lamp Fiber Recoaters
- Three Available Mold Coating Diameters: 280 µm, 430 µm, and 600 µm
- 50 mm or 100 mm Maximum Recoat Length
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. They are available for Ø280 µm, Ø430 µm, or Ø600 µm fiber coatings and in maximum fiber recoat lengths of 50 mm and 100 mm. Custom mold sizes up to Ø900 µm are available; please contact Tech Support for more information. Mold assemblies with a 50 mm recoat length feature a lever to assist with opening or closing the mold.
Recoat material (sold below) is injected into the mold assembly by either an automatic or manual injection system. Then, UV light cures the recoat material. Cure times are dependent on the mold size and recoat material, but they range from approximately 12 - 15 seconds for the RM280A mold assembly with high-index AB950200 recoat material to 30 - 60 seconds with the low-index PC373 recoat material. The recoater mold assembly should be cleaned throughly with isopropyl alcohol or acetone between each recoating process; reliable and repeatable performance is highly dependent on the cleanliness of the mold.
When purchasing a manual fiber recoater for the first time, it is necessary to choose a mold assembly that is appropriate for the desired fiber coating diameter. 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. Because of this, our manual recoaters are adaptable and flexible in the field and can be modified to accept varying diameters of fiber quickly. A recoater mold can be factory installed prior to shipment upon request by contacting Tech Support. It is also necessary to order the proper inserts (sold below) that best match the fiber diameter being used, whether purchasing a fiber recoater for the first time or updating a current recoater for a different fiber diameter.

The manual injector is mounted to the recoater via two 4-40 mounting screws.
- Replacement Manual Injectors for Dispensing Recoat Material into the Mold
- Accept PC373 and AB950200 Recoat Materials
- Replacement Injection Tubes for Recoaters with Manual Injectors
- Replacement Syringe Barrel for Manual Injectors
These manual injectors and injection tubes are available as replacement parts for Thorlabs' Vytran Fiber Recoaters with Manual Injectors; compatible systems are listed to the right. We also offer a replacement syringe barrel.
Each injector can be mounted to compatible fiber recoaters via two 4-40, 3/32" hex screws on the recoater housing (see photo to the right). To connect the injector to the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen by a 1/4 turn to allow for rotation.
The injector is equipped with a distribution valve and two-position selection lever for directing the flow of recoat material. A knurled dispensing screw with an internal plunger acts as a syringe for the recoat material. To fill the syringe, point the lever downward (i.e., toward the recoat bottle), then rotate the knurled dispensing screw counterclockwise until it spins freely to fill the syringe (shown in the photo to the right). Then, to inject the recoat material into the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until near the end of the travel range is reached. Avoid bottoming out the dispenser as this may damage the internal plunger; also take care when re-engaging the threads to avoid cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced within the system. Use lens tissue and an acetone or alcohol cleaning solution to collect any excess recoat material that flows from the mold.
Each injection tube and the RRMS syringe barrel are available as replacement parts for the manual injectors. The injection tube should be changed out if the knurl fitting breaks off the end, it leaks recoat material, or a clog forms that cannot be cleared with acetone. If the syringe no longer injects or an excessive number of air bubbles are visible in the recoat material (even after flushing the system), the syringe barrel should be replaced. A 5/16" thin spanner wrench is required for securing the syringe onto the recoat injector. Detailed installation instructions are provided in the support documentation, which can be found by clicking on the red documents icon () next to each item number.

This handset controller is available as an alternative to the tablet controller previously included with our Vytran Large Diameter Fiber Cleavers, PTR Series Fiber Recoaters, and PTR Series Fiber Proof Testers. One handset controller is included with each new PTR series recoater system. A single handset controller can be used with multiple systems; after configuring parameters for one fiber processing unit, the controller can be disconnected and then connected to a different unit, of the same or a different type, to configure its parameters.
The handset controller must be connected via the included cable in order to use it. The controller automatically turns on when the connected system is turned on. Upon startup, the handset controller will always read parameters from the connected system; i.e., the parameters that appear on the screen will always be the parameters that have been uploaded to the connected unit. If the parameters read from the unit match the parameters of the most recently opened file on the handset controller, the screen will display the file name.
The suite of tools available through the handset controller includes a record of the total cure time of the machine (under Process Counters) that is not shown on the tablet controller. This value may be reset each time the bulbs are replaced.
The handset controller can open, save, delete, export, and import files containing parameters for compatible systems. Exporting or importing a file will require a memory device to be connected to the Program Port of the handset controller.
Instructions for using this controller can be found in the manuals for the compatible Vytran systems.
