| Measuring the near field of sources such as laser diodes, VCSELs, optical fiber, and/or waveguides can be a difficult task. Accurate measurement of such small sources to the micron level requires high precision in the optical and mechanical design. To simplify this task and to fill this requirement, Photon offers several models of Near-Field Profilers (NFPs) covering a wide range of wavelengths and power levels. Another important application of these instruments is to extend the focused laser spot size measurement range of the NanoScan profiler. By expanding the size of a focused spot it is possible to reduce the power density and make possible the measurement of beams that are too powerful to be measured without attenuation, as well as those that are too small to be accurately measured with the standard scanhead. The NanoScan NFPs are easy-to-use turnkey systems that can be used either as a stand-alone instrument or integrated into manufacturing inspection systems. For NanoScan users who want to extend the measurement capability of their present systems, the optical and mechanical components are also available as accessories. The NFP-980 with 60:1 magnification and 1μm resolution, specifically designed for measurement of 980nm pump lasers, is also ideal for other applications in the wavelength range between 700nm–1100 nm. The NFP-1550, with 40:1 magnification and 2.6μm resolution, is designed for use in characterizing sources in the 1300-1600nm telecommunications wavelength band. Both models come with a NanoScan GE/9/5 scanhead and the magnifying objective lens, which can be rigidly mounted to an optional precision XYZ translation stage, which in turn is mounted to an optical rail. They also include the NanoScan Control and Data Acquisition Card and NanoScan Acquisition and Analysis Software. The system has all the standard Windows file saving, printing, communication and ActiveX capability. For visible wavelengths, the NFP-VIS is equipped with the NanoScan SI/9/5 scanhead and the 60:1 microscope objective, AR coated for the 400–700nm wavelength range. UV Wavelengths below 360nm can also be accommodated with an optional UV corrected microscope objective. For higher power and longer wavelength beams the NFP-Pyro is available. These systems can measure spot sizes from 5μm at any wavelength from 190nm to 20μm. This instrument configuration naturally reduces the power density incident on the instrument by one over the square of the magnification. The system can be supplied with a lens for the user-specified wavelength of use. For viewing VCSEL junctions, single-mode fibers and large long wavelength LD junctions there is an optional 100:1 objective lens option, producing diffraction limited performance from 400–700nm with a working distance of approximately 0.25-0.35mm and Numerical Aperture is 0.90. From 700–1600nm, this lens produces near diffraction-limited performance. |
