Reel
- A string is wrapped around an optical fiber bundle to avoid the fiber bundle from tangling
- Bundle diameter is inversely proportional to its bundle length. A larger bundle diameter decreased the bundle length and vice versa

As a leading innovator in glass science and optical design
SUMITA has been working diligently in the field of light and optical glass since its foundation in 1953.
At the time when glass materials were mainly imported, and not produced in Japan,
SUMITA started manufacturing of optical glass, and later established advanced precision processing technology.
Furthermore, from 1960s,
SUMITA has developed its optical fiber technology,
and built an integrated production system that allows manufacturing in-house from glass materials through to finished products.
SUMITA’s optical fiber products have been widely used in the field of medical, communication, measurement, lighting, and optoelectronics.
Now SUMITA produces more than 200 kinds of products,
which range from molding aspheric lenses for cameras, microscopes and endoscopes, optical fibers, to various glass filters and advanced glass materials.
SUMITA has been placed an emphasis on thinking out of the box and a challenging spirit.
Rather than excessive commercialization and corporate profits, we, SUMITA,
have been putting efforts on creating high-value-added products for customers and inspire the world in new ways.
Shining like a glass, bright like a light, we, SUMITA,
keep seeking the infinite possibilities of technological development with our free and flexible mind.

UV Power Monitor/Sensor – SUMITA OPTICAL GLASS Inc.
Ideal for continuous monitoring of output state of UV
UV sensor picks up and displays the ultraviolet rays that eye is unable to perceive. It is a device used for continuous monitoring of UV light intensity. Since SUMITA’s ultraviolet to visible wavelength conversion glass is used in UV-300K, its reliability is high, and it is an optimum sensor device for line inspection in production process. UV-300K enables detecting UV lamp’s deterioration and lighting failure.
