We also have a grade covering from the visible ray (Vis) to the Infrared(IR) regions.
We are the only manufacturer in the global optical industry which can mass-produce CaF2 with a crystal orientation of <111> for this grade.
These are 4K and 8K resolution products developed for TV cameras.
Moreover, we can offer not only raw materials but also polished raw materials, and/or coated raw materials upon request.
