Features of PRISMVUE NF2

Our Unique Optical Prism Design

Uniquely designed PENTAX deflection prisms*¹ allows viewing below the level of direct site, enhances vision and makes it easier to identify small structures in best working posture.
Comfortable surgery is possible without blocking the light of the lighting lamp.
*1 High end deflection prisms [48 degrees]

Bright and wide field of view

PENTAX's unique and sophisticated design provides a bright and wide field of view.
The upright posture facing forward during operation prevents the user's head from interfering with the surgical lights and ensures a bright field of view at all times.

Field width: The field of view is larger by 20 to 30% than
that obtained with conventional products.

Reducing eye fatigue and cervical strain

The convergence (*Note) provided by the optical system allows stress-free parallel viewing at all times.
This reduces the eye fatigue and cervical strain.
*Note: Convergence is the eyes' turning inward towards the nose when we view objects with both eyes.

Easy shifting between magnified and actual-size views

Our loupes allows the user to switch easily between magnified and actual size view by just moving the head and only from the movement of the eyes. This allows stabilization of the magnified viewing position.
*High-refractive-index aspherical lenses are incorporated in eyeglasses for Type L.
