PENTAX Lens Coating Technology
Bringing together technology cultivated through the development of a wide variety of cameras and lenses, PENTAX binoculars have been seeing the world since 1938. Experience the clarity made possible by trusted optical performance and revolutionary coating techniques.
Full multi-coating on all models
- Full multi-coating increases light transmission while preventing flare and ghosting. All models of PENTAX binoculars have these coatings on all lens surfaces and prism incident light surfaces. From the compact U series to our flagship Z series, you can select your binoculars with confidence.
New coatings for even greater light transmittance
- On premium models, design properties have been enhanced and new coatings with the latest film-deposition technology adopted. Transmittance in the visible light range has been dramatically improved through the effective coating of lens and prism surfaces.

Coatings protect lens outer surfaces from water and oil
- Protective coatings have also been applied to objective and ocular lens surfaces that can be inadvertently touched during use. Oil and water droplets and other soiling can be easily wiped away.
