High-Precision Extensometer for Material Testing.
Designed to eliminate the limitations of contact-based extensometers, our Non-Contact Optical Extensometer,Nopix, performs deformation measurements across a wide range of material testing applications fully optically and without contacting the sample. As a high-performance video extensometer, it succeeds where contact-based extensometers fail and with its higher accuracy it can be the modern alternative in all applications where traditional extensometers are used. Nopix is the right video extensometer choice if the application requires no load added to the specimen,tracking multiple gauge points/regions simultaneously and capturing full-field deformation while maintaining high accuracy as well as reliability of the results.

LitestX is our leading universal testing software which is developed for comprehensive material testing.Tools such as data visualization, precise control features, and ready-to-use test templates help you accomplish more in less time. With its sophisticated advanced features and user-friendly interface, LitestX is powerful enough for experts and simple enough for operators at every skill level.

Maximizing customers’ convenience, LitestX is compatible with not only the LitRay but also with all BESMAK products and their dedicated software tools. Plus it works seamlessly with Doli, the major controller device producer, as well as Sematron, our controller device.
A non-contact optical device that measures strain and deformation of a specimen during material testing, using a camera and image analysis instead of physical knife edges.
It uses Digital Image Correlation (DIC). The camera tracks surface points on the specimen in real time and LitRay calculates displacement and strain from them.
Tensile, compression, flexure and torsion tests on metals, plastics, composites, construction materials and more.
ISO 9513 (Class 0.5) and ASTM E83 (Class B1a).
In most applications, yes. It adds no load to the specimen, is not damaged at break, and can track several gauge lengths at once.
Yes. It works with BESMAK machines and with major third-party controllers, including Doli, through analog and serial outputs
