UV to Visible Light Converter Fluorescent Glasses Lumilass – SUMITA OPTICAL GLASS Inc.


Lumilass can convert a faint UV source of 200 – 400 nm light into visible spectrum in high efficiency.

Features

  • Minimum sensitivity of – 1 µW/ cm2 for all emissions.
  • Since a large amount of luminous ions are contained, Lumilass has high sensitivity that allows for visible light detection.
  • Transparent, high in homogeneity.
  • Lumilass has excellent machinability, so it can be processed in various forms.
  • Superior durability and water resistance
  • Lumilass keeps high performance after long-hours irradiation with ultraviolet (UV) light.
  • Available in red (R7), green (G9) and blue (B) emissions.
  • RoHS: Compliant
  • Application: fluorescence microscopy, excimer laser detection, a standard test material for fluorescence characteristics.

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.
