3.1 Fiber optic transmission beam

In accordance with the one-to-one relationship, a number of fine fibers arranged in an orderly array of fiber bundles.

3.2 Industrial optical fiber endoscope detector

Using optical fiber image beam image, through the objective lens observation, with other mechanical and light guide system made for the industrial field is not disintegrated, The apparatus for observing the inner surface of the object to be detected.

3.3 Resolution

The system terminal image has the ability to analyze the details of the target. The unit is. LP/mm.

3.4 Depth of field

Able to obtain a clear image of the imaging range.

Note: the recent objective lens and can obtain a clear image of the point called near sharp point; the most distant from the objective lens and can obtain a clear image point called far point. Close to the point of view And the distance between the depth of the range, called the depth of field.

3.5 Lighting uniformity

Within the effective depth of field of the fiber optic endoscope, the ability to provide consistent illumination to the target object.
