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.

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.
