Sapphire

Al2O3 – 0.4-0.7 µm

Anti-reflective coating on sapphire (Al2O3) for the range of 0.4-0.7 microns. Anti-reflection in other ranges specified by the customer is possible.
The adhesion of the coating is checked with adhesive tape.
The coating has passed the climatic test (24 hours at a temperature of +50 degrees Celsius and a humidity of 98-99%) and mechanical durability (according to the instructions from paragraph 4.5.11 of MIL-C-675C).
Reflection from one surface is shown.
