Microscope for Observing Inner Wall of Holes – PHL200BA

360° Single-shot Observation of Inner Walls!

● Optimal lenses for observing the inner surface of holes with a 360° field of view.

● Utilizes optimal illumination for observing the inner walls of holes ranging from φ8mm to φ50mm.

● Employs lenses with a deep depth of field, ideal for hole observation. Additionally, adjustable depth of field is achievable due to the lens with aperture control.

● Wide-angle observation of inner walls is facilitated through a fisheye effect.

The primary feature of this model

●Feature 1: Adoption of a 178° wide-angle lens (hole inspection lens)

The field of view is as wide as 178°.
As indicated below, the field of vision expands almost horizontally.

360° comprehensive one-shot observation capability

With a fish-eye perspective, it is possible to observe the entire interior surface of the hole.

● Feature 2: Utilization of a fish-eye lens with deep depth of field

You can observe the interior walls of the hole without inserting a lens into the cavity

The aperture ranges from φ8mm to φ100mm, with a depth comparable to the aperture (e.g., around 100mm for φ100mm).
The lens inherently features a substantial depth of field, further adjustable via an aperture mechanism.

You can notice a greater depth of field compared to images captured with fixed-focus lenses.

●Feature 3: No need to insert into the target object, making it less prone to buffering

The Hole Lens has a wide field of view of 178°, eliminating the need to insert it into the hole.
Even if inserted, it only goes a few millimeters, greatly reducing the risk of damaging the target object.
