Front surface Metallic Mirror
1. UV-Enhanced Aluminum: Ravg >90% for 250 - 450 nm.
2. Protected Aluminum: Ravg > 90% for 450 nm - 2 µm, Ravg > 95%
for 2 - 20 µm.
3. Protected Silver : Offers high reflectivity in vis and near-IR
Ravg > 97% for 450 nm - 2 µm, Ravg > 96% for 2 - 20 µm.
4. A durable di-electric coating will be provided on mirrors for
increasing durability and protection from oxidation.
5. No ghost image formation due to First surface being used
for reflection.
