Individual solutions for your industry



Since the 1970s, Stumpe Glas produces filigree glass items for the medical and industrial measuring technology as well as the semiconductor and lighting industry. Manufacturing miniature components is done by a combination of semi automatic machines and the traditional art of glassmaking, called “cold pressing”. In the past couple of years, we developed these methods to perfection. This is allowing us to create almost any individual shape for your high tech product.

The accurate selection of RoHS/ REACH conform raw glass with a high refraction index assures maximum performance and the best possible efficiency.

Whether aspherical, planoconvex, planoconcave, biconvex, biconcave, cross section converters and individual free forms we deliver the correct glass elements for your application. Distortion free flat glass with high transmission or complex, functional coatings complete our portfolio for this sector.
