Grating optical
WebA grating’s visual appearance, unless obviously grossly damaged, should never be used to assess its functionality. The simple fact of the matter is that, except in extreme cases, the … WebGratings Due to the construction of diffraction gratings, the only recommended cleaning method is to use Compressed Air or an Air Blower to remove surface dust. Avoid methods that require any direct contacting of the grating surface. Ultrasonic cleaning should not be used as it may separate the grating surface from the glass substrate.
