Photaron represents the long-awaited dream of
making artificial crystal fluorite from optical glass. It features light
refraction characteristics remarkably close to those of natural crystal
fluorite, while retaining the fluid formability of glass.
Features: Optical characteristics similar to those of natural
crystal fluorite, with no cleavage; high mechanical strength, and thermal
and chemical resistance for greater durability
Applications: High-performance microscopes, cameras, measuring
devices, zoom lenses, optical communications devices, telescopes, pickup
lenses |

Unlike conventional optical glass, with its
abnormal partial dispersion properties, Gadron boasts a refractive index
(nd) of 1.56907 nd, with an Abbe number (vd) of 7l.3. As a result, Gadron
has extremely high abnormal dispensability in both the red and blue
regions
Features: Can be molded with excellent polishing properties,
chemical resistance, and transmittance
Applications: Correction of chromatic and spherical aberrations,
removal of secondary spectra in the red and blue regions |

Ideal for small lot production of a variety
of materials at low cost. All glass products for processing are available
in the required diameter and shape, such as blanks for lenses and prisms.
Features: Small-lot production of various products, superior
workability, high precision, low cost
Applications: Blanks for a wide range of lenses and prisms |

High uniformity of weight makes for high
volume production.
Since the weight of the finished products is close to that of the
original blank, this contributes to greater efficiency in both cost and
configuration.
Features: High volume production, uniform dimensions, low cost,
superior workability
Applications: Blanks for a wide range of prisms and lenses |

Supplied when the diameter of the blank is too small
for hand pressing. The extremely consistent dimensional accuracy enables
high precision processing.
Features: Ideal for both small-lot and high-volume production, with
significant time savings in finishing processes
Applications: Blanks for small-diameter lenses |

Preforms produced directly from the glass
furnace with specially developed optical glass for low-temperature
molding. With the development of gobs, no polishing process is
necessary, realizing higher productivity at lower cost
Features: The same surface finish as polished glass
Applications: Preforms for precision aspheric lens molding |
