PENTAX TTL (Through-the-Lens) Loupes are the world’s first prismatic deflection loupes. PENTAX's unique deflection prisms allow the users to magnify the operation field while standing upright and facing forward.
This allows the users to magnify the operation field without the need to bending their neck down or hunching forward.

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.
Smooth shifting between magnified and actual-size views
Actual-size view can easily be obtained by just rotating the eyeballs downward. There is no need to detach the loupes or flip-up them by hand.
Adjustable Focus
Focus can be adjusted by turning the objective lenses which can be locked to keep the focus.
