We will participate in the “LENS EXPO 2010” and you will be welcome to our booth.

Date: April 21 (Wed)~23 (Fri), 2010
Venue：Pacifico Yokohama, Yokohama, Japan

At this exhibition, we’ll introduce new members of the “H-series” optical glass types highly praised last year.

We will also present “Optical Glass materials (blanks for glass lenses, preforms for precision moldings” and “Optical Lenses (aspherical, spherical)” adopting those new glass types.

In the meanwhile, we will present the “ color compensation filter”.

We will participate “The 11th China International Optoelectronic Expo”. Glad to see you there.

2009 May 22, English and Chinese Website have been opened.
You can see latest Products and Technical Information as Japanese Website.

Renewal greeting

Thank you for your patronage to our optical business. HOYA CORPORATION Optics division renewed the website on April 20th., 2009. You can check the up-to-date information of HOYA optical glass material and the product.

We are greatly appreciated if it brings you good solution for your research and development, optics design, and production technique.

Feature of new website

Our new website is included the following content, and will start soon.

(1) We provide you our new glass group categories, our recommended glass types and our ref1/ref2 glass types.
(2) We introduce you our newly developed glass types as soon as possible.
(3) A new standard and premium standard are set about the refractive property and light transmission characteristics.
(4) We introduce the glass material (preform) refer to the aspherical glass lens.
(5) The property data were updated in some of glass types.
(6) Certain glass types search can be retrieved from n_d -ν_d map.
(7) We put the specified color of each group of glass types, such as our recommended glass types and our ref1/ref2 glass types.

H series (Flagship : 12 types of optical glass)

We recommend the following 12 glass types for high performance that includes leading edge optical glass comprising three families.

(* New)

S series (Standard : 8 types of optical glass)

We recommend the following 8 optical glasses which is balanced between performance and price.

Four Newly Developed Optical Glass Types have been added.

FCD10A (low dispersion and abnormal dispersion glass)

FCD10A is low dispersion (ν_d = 90.20) glass with high relative dispersion (P_{g_F} = 0.5352). It is the next-generation optical glass for an advanced chromatic aberration correction. It is transparent and colorless. It exhibits outstanding internal transmittance.

FCD505 (high refractive index and abnormal dispersion glass)

It is an extremely low dispersion optical glass with the high refractive index glass (n_d =1.59282 ν_d =68.63) even in the low dispersion region. It also has high dispersion (P_{g_F} = 0.5441). It is new optical glass useful in the high resolution of an optical system and optical compactness.

TAFD35 (high refractive index and low dispersion glass)

TAFD35 is new high-performance glass having both a high refractive index and low dispersion (n_d = 1.91082 ν_d = 35.25). Superior polish ability, a high refractive index and a high internal transmittance are coexisited in the glass at a high level.

E-FDS2 (high refractive index and high dispersion glass)

It is the next-generation optical glass with high refractive index and dispersion (n_d = 2.00272 ν_d = 19.32). It has a characteristics of low coloration and high refractive index (λ70 / λ5 = (460)/405) . It is a newly developed optical glass to correspond to wide-angle and high-powered zoom of an optical system.

Five Newly developed glass types for Glass Molded Lenses have been added.

M-FCD1(abnormal dispersion glass material for the molded optics lens)

This material has almost the same refractive index, the abnormal dispersion, and low dispersion as the conventional FCD1 glass. The glass transition point is below 400°C, and the materials is suitable for the glass molded optics lens.

M-FCD500 (high refractive index and abnormal dispersion glass material for the molded optics lens)

Though this is an abnormal dispersion glass with a high refractive index, it is suitable for the glass molded lens because the glass transition temperature (T_g) point is below 400°C.

M-TAC60 and M-TAC80 (high refractive index glass for molded optics lens)

These materials are the next-generation optical glasses for precision molding which have both a high refractive index; n_d > 1.7 and a low dispersion; ν_d > 50. They have a sufficient low softening temperature(T10^7.6)for the precision molding with excellent chemical durability.

M-FDS2
(high refractive index and high dispersion glass material for the molded optics lens)

This is a next generation molded optics glass that has very high refractive index and very high dispersion. This material has low transition temperature (T_g) , and is suitable for the molded optics lens.

Not only Cold Process Preform, but also Hot Process Preform is available. Further information please contact us.
