2014 Jul. 22 NRP®- published in Nihon Keizai Shimbun event

Our NRP® was published in the Nihon Keizai Shimbun (Japan Economic News post) dated 21 July 2014.

Our previous processing of lens material (RP, reheat-pressed product) was molded to a predetermined size that included a flap zone, has been used over the years for spherical glass lenses and was manufactured through the process of grinding and polishing.

The NRP® process that we developed produces lens material shape accuracy improvement (three times higher precision of RP), surface defects less than 1/3 and thickness variation accuracy improvement (5 times over the current company standard) which could significantly reduce the allowance of polishing lens and reduce the processing fluctuation.

2011 Apr.20 High-Transmission, High-Refractive Index and High-Dispersion Optical Glass [ FDS90-SG ] event

The currently recommended glass FDS90, is widely use as a typical high refractive optical glass with high dispersion. However, this glass type has its specific coloration, many of our customers requested the improvement of its transmission.

In order to response the request of our valuable customers, HOYA was devoted to investigate, and finally come to the result of establishing the stablized production technology of the following high transmission optical glass.
We named it as 「FDS90-SG」 (SG:Special Glass, which is particularly for the improvement of transmission.)

This product is positioned as a contribution to the high performance, high function and high quality of optical products.

In addition, only transmission is changed, without any change of the composition of glass and raw material. Also, the price will be same as current FDS90.

FCD100pdf(low dispersion and anomalous dispersion glass)

FCD100 is an extremely low dispersion optical glass equivalent to fluorite (CaF2).      Relying on technological innovation, we have successfully launched the mass production of high-performance optical glass at the apex of the FCD family. Combining it with optical glass of high refractive index allows us to achieve unprecedented advanced chromatic aberration correction.

TAFD55pdf(high refractive index and low dispersion glass)

TAFD55 is an optical glass that achieves a high refractive index exceeding nd = 2.0 and boasts an Abbe number above νd = 29. Moreover, it limits the type of rare metal materials used to obtain maximum cost performance.It also exhibits outstanding spectral transmission, making it the best choice in lenses for high-performance digital products. 

TAFD33pdf(high refractive index / low dispersion glass)

TAFD33 is a new high-performance optical glass, which enjoys a high refractive index that exceeds nd = 1.88 and an Abbe number over νd = 40. It achieves low cost by reducing the use of expensive rare metal materials. 

PCD51pdf (low density and low dispersion glass)

PCD51 is a low dispersion optical glass, featuring excellent chemical durability and low specific gravity.This is a high-performance glass especially suited for reducing optical weght.

Glass Molded Lenses

M-TAFD307pdf(high refractive index and low dispersion glass material for molded optical lenses)

M-TAFD307 is a glass molding material  with a high refractive index made from M-TAFD305, which contributes greatly to high-power lens designs. Moreover, its Abbe number is equivalent to that for M-NBFD10, and it can also be used as a high refractive index glass. We are also able to provide aspheric lenses with the same quality as that of M-TAFD305.

M-FDS1pdf(high refractive index and high dispersion glass material for molded optical lenses)

M-FDS1 is a glass molding material whose refractive index properties equal those of E-FDS1. With the use thereof, the number of choices for high refractive index and high dispersion aspheric lenses ranging between M-FDS2 and M-FDS910 has increased. This enables us to meet a wide variety of needs for high-power lenses.

M-LAC8pdf、M-LAC14pdf(low dispersion glass material for molded optical lenses)

M-LAC8 and M-LAC14 were created to respond to the need for high-performance lens designs more efficient than those for M-LAC130. As a result, the current TAFD~TAC lineup of aspheric lenses featuring a high refractive index and low dispersion has been extended to the LAC series.
