When connecting a camera to a borescope for observation, there may be instances where achieving focus at close range (with a focal distance of approximately 2-4mm) proves challenging due to certain conditions.

For example, when a conversion lens is directly attached as demonstrated below, it may not be possible to perform close-up photography.

In such cases, inserting a close-up ring between the lens and the camera can enable close-up photography.

The minimum focusing distance was verified using the aforementioned combination.
* Employing a 4mm diameter, 0° angle borescope.

In the absence of a close-up ring (approximately 4mm)		Adding a close-up ring (approximately 1.5mm)

The close-up rings introduced herein are available through our company.
