Hoya has continued to lead the world for a long time.
Integrated production from development to
manufacturing is Hoyas competitive strength.
Optical Lenses
and Optical Glass
Optical glass is the business that formed
the foundation for Hoya's establishment in 1941.
Hoya's products, which make use of expertise and echnological capabilities
built up over many years, have won high acclaim from all around the world.
We will continue to strengthen our integrated production system, from the
development of new optical glass materials to optical lenses and lens units,
and achieve further evolution.
Information Technology
Hoya's optical glass business already boasts a history of
more than 70 years.
Hoya provides optical glass materials and various kinds of
lenses and lens units made of optical glass or plastic,
including high-precision, high-value-added products used in
photography-related optical units such as single lens reflex
cameras and compact digital cameras.
In particular, Hoya's glass aspherical molded lenses are
made into lens products that do not require polishing by
directly press molding optical glass melted at high temperatures. Because it is possible to design
lenses that offer excellent correction for aberrations and offer a high angle of view, the number of
lens elements in optical devices is reduced. This contributes to the smaller size, lower weight and
higher functionality of cameras, which are final products.
Since its foundation, Hoya has consistently engaged in operations ranging from accumulated
research and development related to the formation of optical glass to the manufacture of finished
products such as optical lens units. Furthermore, we have established a system enabling mass
production of a variety of products.
