[by Tiana Riggi]  UV/VIS/NIR absorbance spectroscopy is governed by Beer's Law, where the absorbance signal is proportional to chemical concentration, light path length and the compound’s specific molar absorption coefficient. Typical optical pathlengths of cuvettes and flow cells are between 0.1 cm and 10 cm. Longer pathlengths are difficult to achieve due to mechanical constraints. WPI solved this problem with the LWCC Liquid Waveguide Capillary Cells. LWCCs are fiber optic flow cells that combine an increased optical pathlength range from 10–500 cm with small sample volumes ranging from 2.4 µL to about 3 mL. Compared with a standard 1 cm cell you can expect to achieve a 10-500 fold increase in sensitivity.

WPI knows the importance of making measurements where the science happens, and WPI has a full range of reflectance and transmission dipping probes, flowcells and long pathlength liquid waveguide capillary cells, also known as LWCCs with up to 500 cm pathlength that eliminates the need to take a sample to an instrument. Our Photonics Center of Excellence in Friedberg, Germany also allows us to build proven custom configurations quickly. Whether that is a new optical design for a probe, an optical assembly or a customized measurement system.    

[by Tiana Riggi]  From Deep UV to Near Infrared, WPI's optical fiber solutions include a variety of multimode step index designs. In many fields of application in optical sensor and analysis technology, optical fibers and components are required for illumination and for light detection. WPI designs and builds customer-specific fiber assemblies that function reliably with unmatched lot to lot high transmission throughput. Our specialty fiber is one key feature in this in it's the only fiber material currently on the market certified to a DIN standard. The assembly can be a simple 1 fiber patch cord to integrate into your broadband spectrum analyzer to a custom-specific complex fiber transmission probe suitable for difficult environmental conditions. We also offer certified unjacketed bulk fiber.    

[by Tiana Ruchti] When you have exact specifications for your fiber optic assemblies, WPI delivers with proprietary qualified optical fibers designed by in-house optical engineers. You can count on superior performance from WPI's spectroscopy products and the published research scientists who design them. When you depend on reliable data for your discoveries, consider WPI's German Optics Department for qualified optical fiber and assemblies.     Here we discuss the process for submitting a request for an optical fiber to match your needs using the WPI optical fiber selection guide, which is printed in the

[by Tiana Ruchti] Qualified Optical Fiber is a new proprietary product brought to you World Precision Instruments. When you need true plug-and-play optical fibers, you need qualified fiber. Qualified fiber ensures you get consistent measurement results regardless of which fiber you use, even if you switch fibers in the middle of your application. WPI manufactures "Off-The-Shelf" and "Made to Order" high quality spectroscopy fiber and fiber probes. Examples such as transmission dip probes for protein DNA/RNA Quantification, UV Raman Probes for in situ environmental testing of PAHs in aqueouos systems, fluorescence probes designed to detect pH and membrane portential, to standard fiber patch cable to couple to fiberoptic spectrometers, sources and accessories.  

WPI offers custom fiber optic cables and assemblies. This video show how to create a custom ordering code to designate what you need. If you have any questions about ordering Fiber Optic Cables and Assemblies for your laboratory or application, just give us a call (866-606-1974) or email us at wpi@wpiinc.com. More Info
