Reflector
About the glass reflector
The reflector is a key part of the parabolic trough collector, Vicot makes it with quality glass at high shape precision with silver coating for excellent reflectivity, and 6 different layers in total, as shown in next diagram, insures high reflectivity, durable life time and strength.
Features
1. Made of glass with silver coating.
2.Durable, lifetime more than 20 years.
3. Capable of withstanding hailstone.
4. Mirror reflectivity ≥ 93.8%.
5. Strength test: Steel ball of 1cm diameter drops down freely from 1m high.
