PENTAX TTL
Loupes KP303
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.
Easy 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.
Simple and secure wearing with straps
The loupes can be secured using the straps with the stopper.

Features of PRISMVUE NF2
Unique Optical Design
Unique optical design allows prismatic deflection, with a declination angle of 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.
-
High-refractive-index aspherical eyeglass lenses are incorporated.
-
Wide field of view with aspect ratio of 5:6 reduces eye fatigue in binocular vision.
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 toward the nose when we view objects with both eyes
