When observing the inside of the extension kit using a φ4mm bore, the brightness of each camera was compared.
■ 1/2-inch HD camera
Brightness set to the maximum of “100”.
HDR set to “1”.
A 3W illumination was employed, adjusted to the maximum illuminance.
* Despite having a low reflectance and a wide diameter of φ18, in the above combination, there is insufficient brightness.
■ 1/3-inch HD camera
Brightness set to the maximum of “100”.
HDR set to “1”.
A 3W illumination was employed, adjusted to the maximum illuminance.
* Captured for comparison. The brightness of a camera unsuitable for use as a borescope camera.
■ DN3V-200
Brightness set to maximum only for Fine, Rough set to Min.
Gain set to “1”.
A 3W illumination was employed, adjusted to the maximum illuminance.
* Brighter than the 1/2-inch HD camera, maintaining this brightness with Gain set to “1” and Rough set to Min. DN3V-200 ensures sufficient display speed, with a sensor size of 1/1.8 inches and high sensitivity, making it suitable for borescope applications.
