Abstract
This disclosure is directed to an optic having a composited MgO—MgFinfrared anti-reflective coating that is suitable for use in LWIR, MWIR and SWIR ranges, and is particularly suitable for use in the LWIR range. The coated optic disclosed herein passes the severe abrasion test with a barring force between 2 pounds and 2.5 pounds. The MgO—MgFinfrared anti-reflective coating has a thickness in the range of 500 nm to 1500 nm and a reflectance value Rat 12° of less than 2% in the wavelength range of 7.25 nm to 11.75 nm.
