Software Spectra

Software Spectra develops and markets software for designing and manufacturing optical thin film coatings. Its primary product is the TFCalc thin film design software, which thousands of scientists and engineers use in over 40 countries. Why TFCalc?

Multilayer thin film coatings are applied to many optical devices (e.g., lenses, computer monitors, eye glasses, window panes, light bulbs, hot/cold mirrors, x-ray mirrors, photovoltaic cells, infrared detectors, laser gyroscopes, television cameras, prisms, WDM and DWDM filters, VCSEL lasers, etc.) to control the reflected, transmitted, and absorbed light at wavelengths ranging from x-ray to far infrared. A coating's effect is determined by how its layers control the interference and absorption of light.
