MedZense LG20 / LG20-e

The first full spectrum, universal light guide cable and endoscope testing solution Zign Medical is an innovative product development company focused on supplying high quality solutions for the medical industry.

Zign Medical is committed to supporting technical and sterilization departments in hospitals with testing and materials management solutions.

Our products play a crucial role in assuring and maintaining high standards for tools used in hospital OR’s resulting in high quality healthcare for patients.

MedZense testing products

Zign Medical developed the MedZense LG20 and LG20-e to allow hospitals to objectively and efficiently assess the light transmitting quality of light guide cables and endoscopes. It is the first universal solution supporting all major brands of light guide cables and a wide variety of rigid endoscopes. It is also the first solution that tests the cable quality across the visible light spectrum.

Testing your light guide cables and endoscopes helps to prevent bad functioning tools being used during minimally invasive surgery. This results in better light, better contrast and ultimately decreases patient risk, delays and cost. There are two versions available: The LG20 and the LG20-e.


The MedZense LG20 is the only light guide cable-testing device available that supports all major cable fittings. From now on, you only need one device to test a wide variety of cables. This provides flexibility whilst maintaining an efficient testing procedure. Operating the device is straightforward and intuitive. This allows for easy integration in the CSSD process.


The LG20 can be expanded with a separate testing probe for endoscopes. With the probe (PT10) connected to the main unit you can test the full light transmitting system, both cable and endoscope. This allows you to see which part of the system is not performing. Where traditionally the cable is often blamed for bad light, our experience shows that also the light transmission of endoscopes is frequently deteriorated.

Why is it important to measure light performance?

During minimally invasive surgery, it is crucial to have good visibility. Both the light intensity and the composition of light are important. Bad cables and endoscopes can result in either low intensity or in bad contrast due to the composition of light.

Spectrum measurement

Besides testing on white light, the MedZense LG20 measures the light transmission across the visible light spectrum. This unique feature allows you to prevent loss of contrast, especially on red subjects, during procedures. Furthermore, the spectrum analysis shows an early indication of pollution and burn damage of fibers.

Effect of color loss (digital simulation)

Perfect white light consists of light of equal intensity across the visible light spectrum. Due to dirty, burnt or broken light fibers, the transmission of color on the short wave length of the spectrum (blue, then green) decrease faster then the colors on the long wave length side of the spectrum (red). More red light results in decreased contrast on the color red.

Data output ready

The MedZense LG20 is ready for data output. The device stores test results and can push this data to a computer. This creates the possibility to track test results on instrument level and to analyze for quality management purposes.
