Inspection work before endoscope calibration
TIME: 2021-10-14 FROM: HenGal

The endoscope must be calibrated before the inspection and use in order to improve the accuracy in the later inspections. The following Maikete Optoelectronics Instruments will talk about the inspection work before the endoscope calibration.

1. Observe the outer surface of the endoscope under sufficient lighting. The surface of the electroplated parts should be smooth and smooth without scratches and burrs. The surface of the electroplated parts should be uniform in color. There should be no obvious scratches, burns and visible cracks, pinholes, pitting, spots, burrs, paint or The surface of the plastic-sprayed parts should be flat and smooth, and the color should be uniform.

2. The illuminating spot is at the normal working distance. Place a white board on the tested end and illuminate it with immersion transmitted light or the endoscope's own light source. Observe with the naked eye from the eyepiece or monitor. The illuminating spot should fill the field of view without obvious Bright and dark areas.

3. The direction mark of the field of view diaphragm (applicable to fiber endoscopes). At the normal working distance, place a white board on the tested end, and use immersion transmitted light or the endoscope's own light source to illuminate the field of view. The light bar arrow indicates that the direction of the direction mark should be up.

4. Degumming or mildew spots are placed at the normal working distance. Place a white board on the tested end and illuminate it with immersion transmitted light or the built-in light source of the endoscope. Observe with the naked eye from the eyepiece or monitor. There should be no obvious degumming. Or mildew.
