Optical Fiber or Fiber optic is a medium of transmitting data by the pulse of light through a glass or plastic strand or fiber. Fiber optics transmits data in the form of light particles that passes through a thin fiber optic cable. Hence, it is an external transducer and a Photo detector. It works like sensor process. They sense by detecting the modulation of one or more of the properties of light, guided inside the fiber (intensity, wavelength, or polarization), for instance. BIFURCATED FIBER, a fiber optic assembly, contains more than one fiber optic in a single cable. A Y-shaped bifurcated fiber has two fibers side-by-side in the common end and break out into two legs at the other end. The main goal of this assembly is to split a signal or to combine signals. It is used in spectrometers to direct light from sample, to extend the spectral coverage of the measurement and to maintain higher resolution.
Bifurcated fibers are good for directing the light from a source to two different locations, and from a single sample to two spectrometers configured for different wavelength ranges. WPI providing bifurcated fiber has wide range of benefits compared to other products. This being a certified product of WPI, has a wider market acceptance. It is a unique extended range fiber that covers the high UV to long NIR wavelength range. WPI’s fiber resists degradation due to UV exposure better than virtually any fiber on the market. This means less change outs and better data comparison run to run. This Qualified fiber allows true “plug and play” replacement in anywhere. This fiber optics has wide selection of fiber materials and sizes to manufacture the optimum fiber assembly for your application. WPI’s fiber optic assemblies are uniquely designed for biology and physiology applications with small size and excellent photon efficiency. It is uniquely designed for biology and physiology applications with small size and excellent photon efficiency.
A bifurcated fiber can also be used to couple the signal from multiple samples into the same spectrometer and our product is custom configurations for your specific application and customer support with in-house engineering and manufacturing for optical assemblies are easy to specify and quick to deliver.
WPI provides product developers and researchers with UV basic attenuation data by fiber length after manufacturing for starters. DIN 58145:2017-01. The proprietary formulation of the WPI fiber resists UV degradation to a great extent to allow for deep UV down to 185 nm. The UV performance of the fiber is dependent on two parameters; the basic attenuation and the solarization induce loss over usage time.
When you Purchase UV qualified fiber; you receive a certificate for the UV transmission of your assembly after it has been built. Secondly, you receive a certificate of the induced loss generated by continuous exposure to a 30 W deuterium bulb of each fiber material batch from 185-360 nm. The proprietary formulation of WPI fiber allows for excellent transmission of UV light in longer length fiber than has been feasible in the past. This is primarily because of the degradation of the fiber itself over time. WPI’s QUALIFIED OPTICAL FIBERS let you easily clear this hurdle in designing your next product.
Bifurcated Qualified fibers for NIR applications: WPI offer QVLUX fiber for the 700-2200 nm range that works well in demanding petro-chemical, food and pharmaceutical applications. This region is very difficult for standard fibers from traditional suppliers since they cannot control their processes or glass chemistry sufficiently to have the purity required for high-standard of uniformity and superior optical throughput that these applications demand.
Bifurcated Qualified fiber is in UV applications: QVLUX fiber has been engineered to not only provide superior transmission in the UV but have excellent consistency over length. This makes QVLUX a perfect choice for critical measurements or where “plug-and-play” capability is required without having to recalibrate after a fiber assembly change. Standard silica fiber exhibits a “solarization impact” when transmitting light in the UV below ~280 nm. Over time, depending on the optically transmitted power, the fiber’s ability to transmit UV light drops off. Our QVLUX fiber offers superior resistance to solarization, lowest basic attenuation at 200 nm (< 1 dB/m) and the lowest solarization at 214 nm on the market. WPI is the only company offering DIN 58145:2018-01 certified low solarization UV fibers and assemblies for 185 nm to 340 nm. These standard WVLUX fused silica optical fibers are designed for value, but keep in mind that they lose their transmission over time and at high power due to the solarization effects of UV light below 280 nm.
Bifurcated Fiber usage in Life Science Industry. It is of great value in the field of Life Sciences. It offers new approaches to major health problems such as cancer, heart disease, knee disease etc. Fiber optics can be used to replace open surgery therapy. This wide use of optical fiber technique gives us many benefits like solving biological research problems, providing new way of disease treatment, medical diagnosis to name a few.
