Buying Mid-infrared Fibers

Top-level product category: icon fiber optics

More general product categories: specialty fibers, fibers

Related product categories: single-crystal fibers, fiber optics

Mid-infrared fibers are optical fibers designed for efficient transmission of mid-infrared light. These fibers can be made from materials such as chalcogenide glasses, germanate glasses, heavy metal fluoride glasses, sapphire, or polycrystalline substances, each offering unique properties for specific applications.

Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you buy.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying mid-infrared fibers. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

Otherwise, you will need to talk to your technical colleagues.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for mid-infrared fibers. Use the checkboxes to mark possibly suitable suppliers.
  • The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

mid-infrared fibers

LVF offers a large range of fluoride optical fibers, including ZrF4 (fluorozirconate) and InF3 (fluoroindate) fibers designed for mid infrared applications.

  • ZrF4 (fluorozirconate) fibers transmit light from 0.3 µm up to 4.5 µm.
  • InF3 (fluoroindate) fibers transmit light from 0.3 µm up to 5.5 µm.
  • GeO2 (germanate) fibers are qualified for high power handling around 2.7–3.0 µm (Er:YAG and Er:YSSG medical lasers).

LVF fluoride fibers are the most transparent fibers on the market in the mid-infrared 2–5 µm band.

mid-infrared fibers

For the mid-IR spectral range, we produce

CIR fibers transmits infrared radiation in the spectral range of 1.1 μm – 6.5 μm. CIR- fibers with double polymer jacket provides a superior mechanical strength and high flexibility. Low optical losses ensure a successful use of CIR-fiber for a wide range of applications.

PIR fibers are transparent over a broad spectral range 3 μm – 17 μm. Low optical losses without absorption peaks over the mentioned spectral range ensure a successful use of PIR fiber for a broad range of applications.

The HWG design is a perfect option to transmit weakly divergent IR light in the mid IR range from 2 to 18 μm. High performance HWG are produced with double polymer jacket to secure a superior mechanical strength and high flexibility of HWGs.
