We can customize the reflectors according to customer needs, including dielectric mirror and metal mirror, and can produce substrates of different shapes according to requirements.
Reflective bands:
1. Al: 200 nm (UV) ~ 20 μm (FIR);
2. Ag: 400nm (visible) ~ 20μm (far infrared);
3. Au: 600nm (red) ~ 20μm (far infrared).
Advantages:
Al: (1) The only low cost metal that covers UV to IR.
(2) Natural oxide layer (Al₂O₃) provides some protection.
Ag: (1) Optimal reflectivity in the visible region, suitable for high-precision optical systems.
(2) Infrared performance close to gold, lower cost than gold.
Au: (1) Highest infrared reflectivity and corrosion resistance (oxidation, acid and alkali resistance).
(2) Suitable for high humidity or vacuum environments.
