Tecnottica Production

Workshops and components for industrial optics


Tecnottica's production involves different markets and applications, and for this reason is really various and complex. Starting from raw glasses and materials of different forms and kind, we are able to manufacture a wide range of polished and finished optical elements. Tecnottica succesfully works all known materials transparent in the VIS-UV-IR region: from standard optical glasses for lenses, windows and prisms, up to more precious optical glasses at high index and low dispersion, fused silica and UV/IR materials with high transmittance and efficiency. Thanks to a direct raw material acquisition service and to a huge in-house stock, we are able to shorten the production timings for the majority of our components.


All optical glasses and fused silica available from the most famous worldwide producers and suitable for the UV-VIS-SWIR-IR region. Our principal suppliers are:

  • Schott
  • Ohara
  • CDGM
  • Hoya
  • Corning
  • Heraeus
  • ...and many others

Other materials available: ZnSe, ZnS, CaF2, MgF2, Sapphire, Germanium, Silica

Our offer is entirely customizable, differentiated by qualities, tolerances, costs and final applications that customer would like to apply to its own product.

Here below, you can find a general overview of the products that Tecnottica is currently able to manufacture. Please do not hesitate to contact us if you would like to share with us any idea, project, or simple suggestions linked to the manufacturing of other optical elements that are not directly highlighted in this website.

For all the optical surfaces manufactured in Tecnottica, we have available optical coatings specifically studied for UV-VIS-SWIR and IR wavelengths and bandwidths. Furthermore, for some specific optical elements made of glass, a chemical or physical tempering is available.
