Thorlabs 0.1 NA multimode fibers are protected with an enhanced coating material that guarantees long-term performance and reliability. The dual layer acrylate material iseasy to strip, leaving no residue. These coating layers have been specially designed to provide transmission in the near-UV, visible, and NIR ranges 400 - 550 nm and 700 - 1400 nm).  It provides unsurpassed durability and transmission time stability. These fibers can be used with any one of our Ø125 µm outer diameter multimode connectors, as well as many fiber components designed for Ø125 µm outer diameter single mode fiber.

Response from Javier at Thorlabs to schaefer: Thank you very much for contacting us. Although the attenuation of the HPSC series fibers increases relatively quickly as the operating wavelength goes further into the UV, it would be recommendable to use a filter to block any transmission below 300 nm through the fiber. I will contact you directly for further support.

I already have one of these fibers. I am using it with a Halogen lamp which does have some (smallish) UV-emissions. Am I right to assume that most of the UV (below 300nm) will be filtered out by the fiber anyway or do I need an additional filter for that?

A response from Tyler at Thorlabs to stepenofwheele: Thank you for posting your question. We have updated the presentation to include the damage threshold for both CW and pulsed laser sources. I hope this information helps and if you have any further suggestions on how to improve our product presentation, please ask.

What do you mean by high-power? What is the breakdown threshold or power rated at for cw and pulsed?

Reply to srubin from Inge@thorlabs: The material of the core is specified as Undoped Pure Silica, and the cladding is Fluorine doped. We updated our web presentation to include this information. Thank you for your feedback.

What material are the core and clad made of? Is this a Quartz fiber?
