When choosing an industrial endoscope manufacturer, several key factors need to be considered, including field of view angle, light source, bending guidance, imaging quality, material, and length. These factors will directly affect the performance and scope of application of endoscopes, so choosing the appropriate manufacturer is crucial.

1. Imaging quality: Imaging quality directly affects the accuracy and reliability of endoscopic detection. Excellent endoscope manufacturers should possess advanced imaging technology, be able to provide clear, high-resolution images, and have contrast and color reproduction capabilities.

2. Field of view angle: The field of view angle determines the coverage range and observation field of the endoscope. Different application scenarios require different field of view angles, so when choosing a manufacturer, consideration should be given to whether their product line can provide diverse options for field of view angles to meet different needs.

3. Light source: Light source is one of the key factors in endoscopic imaging. High brightness and uniformly distributed light sources can provide clear imaging effects, helping inspectors accurately observe the internal conditions of the object being inspected. When choosing a manufacturer, it is important to pay attention to whether their light source technology is advanced and has adjustable brightness and color temperature functions.

4. Bending guidance: Industrial endoscopes typically require detection in narrow or tortuous environments. Therefore, the ability to bend and guide is one of the important factors to consider when choosing a manufacturer. High quality endoscopes should have flexible bending guidance capabilities and be able to adapt to various complex detection scenarios.

5. Material and length: The material and length of an endoscope have a significant impact on its service life and adaptability. When choosing a manufacturer, it is important to ensure that their products are made of high-quality materials that can resist corrosion and wear, and have sufficient length to meet the needs of different testing depths.
