Material SCHOTT neutral density glass

The function of the wedge stop is to weaken the light beam in a laser scanner.

The wedge stop is made of SCHOTT grey glass. The optical path length remains constant by use of a counter rotation wedge made of a suitable optical glass. In order to obtain the required heat resistance, both parts are fused directly according to the Hellma process. The entrance and exit surfaces are provided with a broad band anti reflection coating for three laser wavelengths.
