Camera attach with borescope

In camera function, we have Dynamic Range.

 

Dynamic range is the numerical value that represents the signal reproduction capability and the ratio between the minimum value and the maximum value in dB (decibel).

 

A camera with high value of dB is less prone to halation even if the object is bright and dark areas are less likely to shade. (High reproduction ability against changes in brightness.)

 

When viewing the interior of a metal workpiece like a borescope with a single lighting, the difference between the direct light and the shadow is large. The camera with a large dynamic range is more suitable for observation.
