Introduction to LED lighting and viewing angle of industrial endoscope probe

The lighting system of the VSNDT industrial endoscope is one of its key components, providing sufficient light for the inspected area to ensure image quality.Common lighting types mainly include:

Fiber Optic Lighting：

Principle: The light from the light source is transmitted to the probe end of the endoscope through optical fiber to illuminate the inspected area.

Advantages: Fiber optic lighting has the characteristics of uniform light and adjustable brightness, and is suitable for various complex environments and inspection tasks.

LED lighting：

Principle: LED is a cold light source. It uses electrical energy to stimulate the LED chip to emit light to illuminate the area to be inspected.

Advantages: LED lighting has the advantages of low power consumption, long life, high brightness, etc., and the color temperature of the LED light source can be adjusted to meet different inspection needs.

Perspective Introduction

The lens viewing angle of the industrial endoscope is one of the important factors affecting its detection range. According to the different viewing angles, endoscope lenses can be divided into wide-angle lenses and ultra-wide-angle lenses.

Wide-angle lens：

Viewing angle range: generally between 60 and 84 degrees.

Features: The focal length of a wide-angle lens is shorter and the viewing angle is larger, so it can capture a larger area of scenery within a shorter shooting distance. Therefore, a wide-angle lens is suitable for objects with a larger detection range.

Ultra wide-angle lens：

Viewing angle range: generally between 94 and 118 degrees, and the viewing angle of some endoscopes can even reach 120°.

Features: The ultra-wide-angle lens has a wider viewing angle and can capture a wider range of scenes. At the same time, the ultra-wide-angle lens also has the advantages of large depth of field and small distortion, which is suitable for occasions with higher requirements for the detection range and need to capture more details.

In summary, the probe lighting types of micro-viewing photoelectric industrial endoscopes mainly include fiber optic lighting and LED lighting, which have the advantages of uniform light, adjustable brightness, low power consumption, and long life. At the same time, its lens viewing angle includes a variety of types such as wide angle and ultra-wide angle, which can meet different detection ranges and detail requirements. In actual applications, users can choose the appropriate lighting type and lens viewing angle according to specific needs and detection environment.
