Apparatus and method for testing a reflector coating |
摘要 |
A method of testing a coating on a reflector having a first focal point includes placing a mirror at the first focal point of the reflector and angled to orient with an area on the coating. Electromagnetic (EM) radiation is directed to the mirror which then directs the EM radiation on the area. The EM radiation which is reflected from the coating is collected onto a sensor disposed at a second focal point. The intensity of the EM radiation collected on the sensor is detected.
