In this research we report the design and fabrication of metal – all dielectric thin film mirror for 3-5 micron range and for normal incident angle. This 3 layer mirror was deposited on BK7 substrate in 10-6 mbar base pressure by Electron gun and thermal filament. Quartz crystal was used for thickness control. High advantages of this mirror are environment durability, mechanical hardness and clean ability. Spectrophotometery results show that the reflection of this mirror in 3-5 micron range is higher than gold.
