Fiber heaters process optical fibers and composite wires that can be inserted into the Fibheat units through the lateral slot (gap). See the pictures below.
What are Fiber heaters used for? Tapering, fiber couplers, selective heating, and joining.
What is tapering of fibers? Tapering of fibers, e.g., optical fibers, is done by heating a small fiber region to a high temperature while the fiber is gently stretched as evenly as possible. Tapering reduces the diameter of the fiber and heated core.

MHI Fiber Heaters may be used in horizontal and vertical orientations with the stand shown below. The Fiber Heaters are beneficial for optical fiber processing, especially fiber coupler fabrication or coning. Dimensions are available by calling 513-772-0404 or clicking on Contact Us. The heated fiber temperature will typically be lower than the heating element temperature (depending on the fiber). Thermocouples are not shown in the pictures above but in the image below. Thermocouples are included. Specialty FibHeat200-XRD model Fiber Microheater with Fiber-Heater available. X-Ray and Neutron Beam Ports for high-temperature testing are shown below. Photonic materials processing/testing is feasible. Note that high-power units have slightly slanted slots to accommodate multidirectional use ports. MHI provides a calibration curve custom to your application. Nominal uniformity profiles (only when available) are also available by contacting us. All MHI Fiber Heaters utilize MHI’s patented heating elements. Note that slot and hole directions are interchanged in the 75mm version. See further below for more description. MHI’s BPAN-O-PLUS and Data Acquisition System closed-loop control system, with over-temperature protection, is available for MicroFiber™ Heaters and Fiber Heaters. Compare the price with the online form below. Please visit the testimonials page for references./ MHI Control Panels will be shown on the quote when requested. Please inquire about UL and cUL. |

The thermocouple location is shown below in the photograph. Please note that the exact location differs between models or maybe located to not interfere with a sample or a beam. A typical MHI multi-axis flexible stand for the fiber heaters is shown below.
The profile varies with installation and fiber slots sizes. It is very uniform – regardless the ends can be cooled to get sharper drops.
