Ohara GmbH will present our products at the following exhibition:

LASER World of PHOTONICS
May 23rd until 26th 2011
Munich, Germany


New optical glasses (Date: 06/2010)

S-FPM2

Introducing S-FPM2, an anomalous dispersion glass in the intermediate refractive index region that is easy to handle when processing and cleaning, thanks to the excellent balance between wear rate and acid resistance.

By combining it with a glass material of high refractive index and high dispersion, this product can be effective for correcting chromatic aberration and manufacturing compact lens units.

S-LAH55V and S-LAH65V

S-LAH55 and S-LAH65 have been used generally as optical materials for replacement lenses of digital cameras and single-lens reflex cameras. The composition of these glass materials has been optimized to reduce costs, while maintaining optical and processing properties. We recommend these materials as new S-LAH55V and S-LAH65V.

L-BBH1

Introducing the low Tg optical glass L-BBH1 in a new dimension that simultaneously achieves a refractive index in excess of 2.1 and a mold pressing temperature below 400ºC.



Length stability over time (Date: 12/2007)

Even on a constant temperature, CLEARCERAM®-Z shrinks very slightly over time.
Typical shrinking rates L/L that have been measured for the material samples are about 1x10-7 per year at room temperature. *1

L = Shrinking length of sample per year     L = Sample length

*1 The measurements were performed at PTB’s Precision Interferometer.



New optical glasses (Date: 05/2007)

S-LAH71

Combined with our low dispersion glasses, S-LAH71 can lower chromatioc aberration effectively. Development of this new type was triggered from production of digital cameras.

S-NBH52 and S-NBH53

These types show a low flourescence intensity, high transmittance and abnormal dispersion. S-NBH52 follows BPH35 which is not available any more since a longer time, S-NBH53 is derived from S-TIH3. We see typical applications in mikroskopy.

S-NBH55

Combined with our low dispersion glasses, S-NBH55 can lower chromatioc aberration effectively. This type do not tend to devitrification so production of large parts and moldings is possible. Typical field of application can be television cameras and large-size projection optics.



Ohara to discontinue production of S-NPH6:
(Date: 09/2005)

Due to low demand the production of S-NPH6 will be discontinued. Please contact Ohara GmbH for further information.


Ohara to discontinue production of S-FPL52:
(Date: 11/2004)

Due to a continuing inconsistency in melt yields, our production of S-FPL52 will be discontinued. This will open up melting capacity for our higher demand glass types S-FPL51 and S-FPL53. Please contact Ohara GmbH for further information.
