Precision Intros Wavelength Meter

BOULDER, Colo. -- Precision Photonics Corporation, specialists in wavelength measurement and control, announces the production release of the SW1500 Sweepmeter (TM) ultra-precision wavelength measurement platform. The Sweepmeter enables the use of tunable laser instruments in applications where much greater wavelength accuracy is an absolute requirement. The Sweepmeter technology is the first to provide real-time, sub-picometer absolute wavelength measurement for any commercially available swept tunable laser, with a NIST-traceable calibration of every scan. This real-time measurement can improve the accuracy of a typical tunable laser instrument by as many as two orders of magnitude, approaching accuracies formerly only possible with fixed wavelength gas lasers. The Sweepmeter technology provides unprecedented accuracy to measurements made with swept tunable lasers. As examples, next-generation DWDM components must be measured as a function of wavelength with sub-picometer accuracy, in real-time, at scan rates of hundreds of nanometers per second. Advanced lithography demands sub-nanometer absolute dimension control of optical components, which is enabled by sub-pm tunable lasers. To meet these needs, the Sweepmeter delivers a high speed digital clock signal, where the wavelength of the laser at each clock tick is known to sub-picometer accuracy. The Sweepmeter’s clock output feature precisely synchronizes wavelength and time to sub-picometer levels, and allows rapid reduction of data to results.The unique real-time Sweepmeter technology from Precision Photonics allows customers to conduct test and measurement procedures with far greater accuracy than previously possible. The accuracy of every scan using a Sweepmeter is traceable to absolute standards kept at the US National Institute of Standards and Technology (NIST). The Sweepmeter is configured to work with any swept wavelength system, providing dramatic improvements in accuracy and throughput. The Sweepmeter is available as either a stand-alone instrument, or card-mounted for cPCI and PXI chassis. “Real-time NIST traceability eliminates ambiguity in comparison of measurements taken at different times or locations within a facility or even between facilities world-wide. The open standards we support permit customers to assemble a best-of-class test station using the optimum modular solutions, saving money and increasing throughput. But perhaps most importantly, we hope to broaden the applicability of tunable lasers with our technology, which makes these lasers much more accurate, even approaching gas laser standards,” states Chris Myatt, CEO.
