Request InfoPhotonic Characterization Tool Gatan Inc.PLEASANTON, Calif., Sept. 18, 2009 – Gatan Inc. has launched the MonoCL4, a photonic characterization tool that performs spectroscopic analysis with high spatial resolution and depth of field based upon the power and flexibility of an electron probe. As a next-generation cathodoluminescence (CL) system, it is used in high-resolution CL imaging, spectroscopy and spectrum imaging. CL is suitable for a wide range of specimens including microcharacterization of the optical and electronic properties of semiconductor and optoelectronic materials, and observation of parts-per-million changes in mineral chemistry.
