Real View® Polarized Micro Sample Observation Unit
This is an optional polarized light microscopic observation unit for the NEXTA® DSC series thermal analyzer.
It is a camera unit equipped with a high resolution camera and polarized light feature. Together with our unique image processing technology, it can allow you to make successful analysis in challenging applications such as detecting melting point of fish eyes *1 in polymer films, observing the crystallization process of crystalline materials, and analyzing melting point of Multi-layer films.
In the filed of, for example, high-functional film manufacturing, this optional camera unit can be used for identifying process improvement areas for reducing fish eyes in film molding, basic research on crystal orientation of materials, quality control and failure analysis of multi-layer films.

Features
Use of high resolution cameras enables you to observe small areas
The high resolution camera provides digital zoom up to 50 times. You can observe small areas of your samples that cannot be observed with our conventional cameras.
Melting point analysis by polarized light and image processing
Our unique image processing technology realizes melting point analysis of very small areas, which is difficult to detect with conventional DSC. Now you can analyze melting point of fish eye and multi-layered film by each layer. All you do is, first try to capture clear and sharpened image using the polarized light adjusting unit, then carry out measurement in the same way as normal DSC.
[Melting point analysis method]
The derivative of the brightness (luminance) signal curve shows the same trend as DSC curve. The melting point can be detected by reading the peak top of derivative curve.
