LVis is a graphical user interface for ORTECs GammaVision® Gamma-Ray Spectrum Analysis and MCA Emulator software (A66-BW), designed for use in counting laboratories.

LVis is an “application manager” product. It uses the underlying software components of GammaVision to control acquisition hardware, and to manage the gamma spectroscopy samples in a counting laboratory. The analysis itself is performed using the tried-and-tested analysis capabilities of GammaVision itself. LVis provides a sophisticated sample automation environment to control acquisitions and analyses based upon pre-determined “parameter sets” which allow entry of sample-specific data by a technician as needed, while pre-loading automatically that information which can pre-specified by an expert or supervisor. Because LVis relies on core functions within GammaVision, the two applications must be used together.
