Free form mirrors normally are symmetrical relative to the optical axis but Nalux has the capability to take the design a step further if necessary and could even make the mirror completely asymmetrical such as a saddle shape.
Because we have the capability to make free form mirrors, Nalux can even reduce the number of mirrors or other optics in a system because color correction or other correcting optics aren’t needed due to the mirror’s more advanced shape.
Nalux has patented measurment methods that allow for the accurate measurement of a free form mirror.
Free form mirror surface accuracy can be sub micron and the reflectance is 95% when using Nalux’s highly reflective aluminum coating which doesn’t deteriorate at high temperature and high humidity testing(the temperature: 65℃, the humidity: 90%).
