MT-CRS-FDS LASER FILM SCANNERThis modular laser film scanner is part of the CRS family of beam dosimetry accessories. Major components of the laser film scanner are directly interchangeable with the CRS water scanner, eliminating duplication of several components.

The film scanner may be configured as a stand-alone system with dedicated mechanical components and electrometer. It can also be quickly assembled using the existing scanning mechanism and electrometer from the CRS 2D or 3D water scanner.
