Effective immediately, SCHOTT supplies fire-polished glass rods that are only millimeters in thickness and up to 1000 mm long for efficient manufacturing of small lenses

The length of the rods enables considerably higher yields, while the smaller diameter results in a decreased loss of material during manufacturing of smaller components. The fire-polished surface of the rods is already suitable for a variety of applications. After all, the new dimensions of the rod ensure easy processing and reduce the processing time significantly.

SCHOTT Advanced Optics has expanded the availability of optical glasses suitable for the precision molding process.

In addition to the already established P- and N-glasses the following glass types have additionally been successfully tested for the precision molding process: N-KZFS2, N-KZFS4, N-KZFS5, N-KZFS8, N-LAF33, N-LASF46B and SF57. We have further improved the N-LASF46A. The new variety N-LASF46B (nd= 1.90366 ; vd = 31.32) posses a significantly improved transmittance in the blue area (at 400 nm, 10 mm) = 85% and is also well suitable for the precision mold process.

The glass types N-KZFS4, N-KZFS5, N-KZFS8 are part of the special short flint glasses that SCHOTT offers but feature particularly high transmission within the blue-violet spectral range combined with a remarkable low fluorescence at an excitation wavelength of 365 nm. These glasses that SCHOTT also refers to as “True Color” glasses are being used more and more frequently in the fluorescence microscopy because they are ideally suited for realizing correction apochromatic designs

SCHOTT LASF35 high index glass with superb transmittance in the blue

The recently achieved combination of outstanding nd and d values together with excellent transmittance especially in the blue spectral range makes LASF35 glass one of the most preferred optical materials for optical designs.

SCHOTT Advanced Optics has a wide range of capabilities for shaping and light-weighting of ZERODUR®. With grinding up to 90% weight reduction can be achieved. Subsequent acid etching can be used to raise the strength of the structure significantly.

Detailed information may be found on our Application Datasheet:

Optical glass from SCHOTT Advanced Optics is not only found in industrial, safety or medical industries, SCHOTT material is also well suited for applications in Art, Architecture and Design and a significant number of artists use it for either artistic or architectural projects.

We have expanded our range of optical glass types with the addition of 2 new glasses N-SF2 (n_d = 1.64769; v_d = 33.82) and N-KZFS5 (n_d = 1.65412; v_d = 39.70).

All data sheets of our new glass types are available for download from our website.

P-SF8 has specifically been developed for the use as aspherical lens and can be precision molded due to its low glass transition temperature. It is available in various forms of supply, such as polished balls, polished spheres and discs, precision gobs, rods and pressings.
