1. What is the difference between a metal film and an endothermic film?
The metal film is produced by a magnetron sputtering process. A large amount of metal elements are added and the has a good reflection ability to the infrared film. It is insulated by the principle of reflecting infrared rays. The absorption film is added with an infrared absorber during production and the infrared is absorbed by the film. It is insulated by the bsorption principle and secondary heat radiation will be generated after the heat absorption is saturated.
2. Why are 1400nm instruments so much more expensive than 940nm instruments?
It's all about the cost of raw materials. The cost of a 1400nm light source and receiver is much higher.
3. Can the window film transmission meter measure the insulation rate?
Our instrument measures the infrared rejection rate. The higher the infrared rejection rate, the higher the thermal insulation rate. Because visible light also has a small amount of heat, in the strict sense, the heat insulation rate needs to integrate visible light, infrared and ultraviolet heat insulation data. Ultraviolet heat is very small and visible light is beneficial. Therefore, infrared is the main source of heat, so the infrared rejection rate is basically equivalent to the thermal insulation rate.
