Precision Molding

Präzisionsblankpresste Linsen

From custom design and prototyping through to series production of double-sided aspheres, off-axis aspheres, and acylindrical lens arrays both in the visible and infrared range of the spectrum. We are the independent supplier of precision-molded glass optics.


What we offer

  • Double-sided aspheres
  • Off-axis aspheres
  • Acylindrical lens arrays both in the visible and infrared range of the spectrum
  • VIS to NIR with oxide glasses
  • SWIR to LWIR with chalcogenide glasses
  • Custom design
  • Prototyping
  • Series production
  • Independent supplier of precision-molded glass optics


AS9100D / ISO 90001 certified and ITAR-compliant US production site and Swiss manufacturing site without ITAR restrictions.

FISBA has many years of experience with this process, which makes the production of aspheres and cylinder lens arrays in medium to high quantities possible at competitive pricing.

Components can thus be manufactured that would not be feasible with conventional processes, especially in the area of very small aspheric and non-circular cylindrical micro-optics.

In addition to the pressing machines in the clean room area, our production at the St. Gallen (Switzerland) and Tucson (Arizona, USA) sites is enhanced by different complementary technologies:

  • In-house Production of Pressing Tools with Ultra-precision Grinding and Diamond Drilling
  • Centering Grinding and Non-rotationally Symmetric Grinding of Outer Contours
  • Cementing of Optics and Mounting of Entire Optical Systems
