Customer Reviews
The touch screen micro vickers hardness tester has been installed a few weeks ago, everything is OK. Thanks for your advice and excellent service.

—— Mr. David Chambers

Thanks for the fast delivery and our customer is very satisfied for the rockwell hardness tester, and hope more orders soon.

—— Neil Renato

After we visited the customer, they finally decided to purchase Brinell hardness tester iBrin-413Z, now we have installed the unit at customer’s site,

—— Fermin Lee

Thank you for the indenters (diamond  cone 120 degrees). We recently got it and already tested it. Indenters  are good as we expected. 

—— Dalius Skinulis

The Measurements are good for Brinell Tester HBST-3000.

—— Sun Chull Kim

Hey, the hardness tester iVick-484ST was installed last week and works well, thanks for the professional support.

—— Sabinian Smith

I am glad to inform you that the installation of the SHB-3000C Brinell hardness tester has been finished successfully. I would like to thank you!

Differential Interference Contrast (DIC)
Latest company news about Differential Interference Contrast (DIC)

 

Differential Interference Contrast (DIC), also known as Nomarski Contrast, helps to visualize small height differences on the specimen surface, thus enhancing feature contrast.

 

DIC uses a Wollaston prism together with a polarizer and analyzer whose transmission axes are perpendicular (crossed at 90°) to each other. The two light waves split by the prism are made to interfere after reflection from the specimen surface, rendering height differences visible as variations in color and texture.

 

For the majority of cases, incident light microscopy provides most of the required information, but for some cases, in particular polymers and composite materials, transmitted light microscopy (for transparent materials) and the use of stains or dyes can provide insights into the microstructure that would remain hidden when using standard bulk sample preparation and normal incident illumination.

 

Because many thermoset materials are inert to common metallographic etchants, the sample’s microstructure is often best observed with transmitted polarized light to enhance the differences in refractive index of discrete features.

Differential Interference Contrast (DIC): DIC visualizes height and phase differences. A Wollaston prism splits polarized light into an ordinary and an extraordinary wave. These waves vibrate at right angles to each other, propagate at different rates and are physically separate. This results in a 3D image of the sample surface, although no real topographical information can be derived from it.
