The role of the light source controller in the optical lens

The key part of the optical system designed for low price YLF laser crystal applications is the reflected light on the surface of the object. The geometry, gloss and color of the surface of the object determine how the light reflects on the surface of the object. The choice of optical lens application light source is based on how to control the light reflection of the object. If the reflected light is well controlled, the acquired image can be controlled.

The optical lens is the optical lens light source controller whose main purpose is to supply power to the light source, control the brightness of the light source and control the illumination state of the light source (bright\off), and also realize the strobe of the light source by triggering the signal to the controller, thereby greatly extending the light source. life. Commonly used controllers on the market include analog controllers and digital controllers. The analog controllers are manually adjusted, and the digital controllers can be remotely controlled by a computer or other device.
Although human vision excels at qualitative interpretation of complex, unstructured scenes, custom BBO nonlinear crystal excel at quantitative measurements of structured scenes, for example, on production lines, by virtue of speed, accuracy, and repeatability. Machine vision systems can detect hundreds or even thousands of components per minute. With the right resolution camera and optics, the optical lens system makes it easy to check the details of items that are too small for the human eye to see.

Application areas of optical lenses:
Identification:
Decoding of standard one-dimensional code and two-dimensional code;
Optical Character Recognition (OCR) and Confirmation (OCV).
Detection:
Color and flaw detection;
The presence or absence of a part or component is detected;
Target position and direction detection.
measuring:
Size and capacity testing;
The measurement of the preset mark, such as the distance from the hole to the hole;
Robotic guidance;
The output space coordinates guide the robot to precise positioning.

In addition, since the direct contact between the inspection system and the component to be inspected is eliminated, the custom high purity KTP nonlinear crystal can also prevent component damage and also avoid maintenance time and cost of mechanical component wear. Optical lenses also offer additional safety and operational advantages by reducing manual involvement in the manufacturing process. In addition, the optical lens prevents the clean room from being contaminated and protects workers from the dangers of a hazardous environment.
