Olympus Endoscopy System – We are constantly developing new technologies to bring new value to scientific development. At the same time, we continue to try more possibilities in the field of endoscopic therapy. Now, we’re focusing our technology on a smaller but more valuable device for endoscopic screening. It was impossible before, but now it has become a new standard.


main features

HDTV imaging capability provides the best image quality for endoscopy, and can observe capillary, mucosal structure and other patterns.

NBI (narrowband imaging) enhances visibility of capillaries and other structures to mucosal surfaces.

The new design uses long-life LED light source to minimize lamp replacement, while reducing energy and noise.

The pre-freezing function automatically selects the clearest still image. This may help save time and eliminate doctors’frustration.

There are two types of structural enhancement that are feasible – mainly conventional type A is the ideal choice for observing larger mucosal tissues with lower gastrointestinal contrast and higher gastrointestinal contrast, while new type B is suitable for observing vascular tissues of upper gastrointestinal tract.

Compatible portable memory (MAJ-1925), which is the standard of data management. Just connect and upload.

Compatible with EVIS 100/130/140 series, AoZhi150 series, EVIS EXERA 160 series, EVIS EXERA II 180 series and GI/BF/VISERA series endoscopes. * Please note that there are some exceptions.

The output of 16:9 And 16:10 is available for HDTV display. Compatible with analog signals, HD-SDI and DVI output.

Compact Design Using LED Technology

The CV-170 image processing device has built-in LED lights, which are sufficient to achieve the brightness level required for observation. In addition, because the LED light source has a longer life, so there is little need to replace the bulb. In this way, maintenance time and operation cost are greatly reduced.

Compatibility of Portable Storage Devices

Portable storage device (MAJ-1925) has become a recognized standard for data exchange. Olympus now provides a CV-170-compatible memory port. A high-speed portable 2GB memory can be compatible with computers. CV-170 will automatically transfer the collected pictures to the memory. You can also download the information of the computer or other recording devices to the memory. This saves system settings, user preset information and patient data. The high-speed recording of this memory makes data management fast and efficient.

Special Display LMD-1951MC

19-inch liquid crystal display, high brightness, high contrast and excellent picture restoration

Various display modes, including mirror screen and picture-in-picture mode, can view different real-time images at the same time.

Support a wide range of input/output ports, including composite, Y/C, RGB/component, HD15 and DVI-D input. The built-in optional port can realize the input/output of HD-SDI/SD-SDI signal.

Special trolley TC-A5

Compatible with all kinds of OLYMPUS equipment (except EUS equipment), equipped with large-scale monitor (such as OEV262H), effectively accommodate equipment cables, simple and compact, uniform appearance, saving endoscopy room space.

Olympus ENF-VT2 nasopharyngeal laryngoscope provides users with excellent observation ability and therapeutic performance. Its high-quality imaging, clear vision and higher accuracy enable high-resolution office therapy through nasal laryngoscopy/vocal cords and pharynx procedures.

Olympus ENF-VT2 Nasopharyngoscope

High image quality, pay close attention to observation.

From inhalation to biopsy, there may be a wide range of treatments.

High quality imaging

ENF-VT2 provides some of the brightest and clearest images in video mirrors, making observation easier and diagnostic in detail.

NBI compatibility for early lesion detection

Narrow-band imaging (NBI) observation – in NBI-compatible video systems – enables users to identify small lesions at an early stage, thus contributing to early cancer detection.


2mm close-focus function for image enlargement

Close focus allows close observation of 2 mm tissue to obtain detailed views during mucosal observation, such as very accurate biopsy.
