Lumatec liquid light guides

One ingenious idea, countless applications   

Series 380 – A broad spectrum from near-UV to far-red

We designed Series 350 light guides to deliver high-intensity white light ranging from near-UV to far-red. These robust devices stand up well to the wear and tear of harsh conditions.

Liquid light guides – the perfect alternative to silica fiber bundles

Liquid light guides are clearly superior to light guides made of silica fiber bundles by the very nature of their design. A liquid light guide is much like a single silica fiber with a very large diameter. It has the cross-section of an open pipe, transmitting light with total reflectance using all the space available. Silica fiber bundles, in contrast, are like many small tubes in a larger pipe with spaces between the individual strands remaining unused. These dead spots do not transmit light. This is why our liquid light guides are able to deliver light with much greater intensity to the target object.

Liquid light guides - flexible in more ways than one

Our liquid light guides consist of a polymer tube with a liquid core. They do not break. Bundles of optical fibers, in contrast, will fatigue if they are frequently bent and eventually break. LUMATEC liquid light guides have much larger apertures, are more efficient and serve many different applications. They are the perfect solutions for applications that demand uniform, high-intensity light. We offer devices designed for diverse spectra ranging from ultraviolet to infrared and a broad selection of end fittings.

Feel free to talk to us if you wish to learn more about our liquid light guides. We'll be happy to discuss which options are best suited for your purposes. The possibilities are many, and we're always exploring fascinating new applications with our customers.

The few limitations of our liquid light guides

There are not many constraints that limit our liquid light guides' use. One of the few is that their cross sections have to be circular; another is that they can only tolerate extreme temperatures for short periods. Apart from the end fittings, which are very robust, they work best in environments that people find comfortable.  

Four proven standard light guides

To date, we have developed four types of liquid light guides that differ mainly in terms of their liquids' optical properties. The charts and tables below show the various transmission spectra and other specifications of our light guides. Our light guides are available in various cross-sections and with a range of sleeve types to fit your needs. We also offer a selection of connectors with up to four poles.
