  • Official site

Diameter 1.8mm. With an extremely small focal length, it reaches the side wall welds of fine holes.

This product is a rigid industrial endoscope with a diameter of 1.8mm. The insertion part uses a stainless steel rigid tube, and the depth of field is 1 to 20mm. It allows for clear observation of details of the object even at extremely close distances. Due to the rigid tube, it is suitable for inspecting welds in piping materials where the internal passage is linear. It is particularly recommended for cases where you want to insert it through a tiny hole and observe the welds on the side walls of the hole at close range.

Applications/Examples of results

In the field of welding, gaps or welding defects can occur inside products after welding, which can directly affect the quality of the product. However, when the weld is located internally, it is difficult to check the condition from the outside, making visual inspection challenging. With general industrial endoscopes, due to the relationship of focal length, if you get too close to the object, it may not focus properly, making it difficult to clearly observe the details of the weld located at a very close distance. This product is a rigid side-view endoscope with a focal depth of 1 to 20 mm and a diameter of 1.8 mm. It allows for clear observation even at a close distance of about 1 mm from the object, enabling detailed inspection of internal welds through tiny holes or narrow spaces. In particular, it is suitable for inspecting welds and gaps on the side walls of tiny holes inside pipes, supporting close-range inspections that are difficult to perform with standard endoscopes.

Detailed information

    The rigid tube can be removed and replaced, allowing for flexible adaptation to various applications. The tip can be rotated 270 degrees, enabling adjustment of the observation direction according to the inspection target. Additionally, it is equipped with dedicated shortcut buttons for dimming and photography, allowing for quick adjustments of brightness and capturing images. It offers excellent operability, facilitating efficient inspection work.

    The side-view lens has a structure that differs from a typical direct-view lens, as it is positioned on the side and near the tip of the insertion tube. In some side-view endoscopes, the lens is located near the center of the insertion tube, which can make it difficult to adequately observe the condition near the bottom when the tip comes into contact with the surface being examined. This product is designed to make observation easier from a position close to the bottom of the object being examined by placing the lens on the upper side near the tip. Furthermore, the depth of field is short, ranging from 1 to 20 mm, allowing for clear observation even from very close distances to the object. It is suitable for inspecting welds in tiny gaps and at close distances where conventional endoscopes may struggle to focus.
