In this molding process, since anti-reflection coating is applied to both sides of the light-transmitting window 13, the reflection of the light beam 14 on the surface of the light-transmitting window 13 is extremely small, and almost no light energy loss occurs. Incidentally, even by simply applying anti-reflection coating to only one surface of the light-transmitting window 13, a corresponding amount of light reflection can be prevented.
