Demonstration is OK, so please inquire.
        Fullauto StrainEye LSM-9100W/WS is a fully automatic 2D-measuring device which measures retardation values up to 3000nm and the direction of a slow axis in a transparent body having strain and birefringence therein.
        In order to measure direction and birefringence, conventionally the visual observation type polariscope using the Senarmont method is used. As well, our in-house manufactured product, Semiauto Senarmont which performs semi-automatic operations with the analyzer only manually rotated is also used.The Senarmont method is an inspection method for measuring retardation quantitatively. An operator rotates the analyzer so that brightness of the part to be measured changes from the brightest state to darkest state, and measures its retardation by rotating the analyzer angularly.
        However, this conventional type has a problem such as the difference in decision of the brightness due to the difference in the condition during the measurement and also due to the difference in skill of each operator. Moreover, in Semiauto Senalmont, although the accuracy of measurement has improved from the visual observation type, the area to be measured is defined to the specific small portion in an image.
        This Fullauto StrainEye makes it possible to start measuring immediately by only putting a sample on the polarizer. Therefore, retardation values and the direction of the slow axis can be measured easily. The measurement result is not influenced by each pixel of differences of personal skill. Not only a specific part is not subjected to the measurement but all of each pixel of a built-in CCD camera measures the entire detecting part. Since the direction of retardation and a slow axis are 2D-displayed on a monitor, those direction states are recognized immediately by the operator.
       This instrument is suitable for measuring small samples since possible picture area is optionally variable from 60mm x 60mm to 10mm x 10mm based on being equipped with x6 magnification optical zoom lens for taking images.This device is connected with a PC, and it is therefore feasible to save not only the measured data but also the observed image data easily.With the use of super-luminescent LED as a light source, this detector is designed for long life and low power consumption. Accordingly maintenance and replacement of the light source as well as running costs can be reduced or dispensed with all together.
