Developer's description:

SpectraShop is a program for measuring, analyzing and storing visible light spectra. It can measure spectra directly with various instruments, or import data from other programs. Spectral data can also be exported in several formats. In addition to individual specimens, SpectraShop has a very flexible chart definition and measurement feature. An impressive array of colorimetric values are displayed for each spectrum. Easy to use tools are provided for analyzing and visualizing spectral and colorimetric data.

This is a fantastic version with lots of great new tools, along with enhancements to your existing ones. All the tools are designed to have great power yet present an easy to use interface.
