Spectrilight™ Control Software

The SpectrILight software package puts complete control of data taking in the user’s hands. Wavelength range and resolution, exposure time, scan averaging and smoothing, batch and pre-scheduled data collection are all handled. The % Transmission/Reflectance and Irradiance measurement displays can be exported to ASCII text, Excel®, BMP or SPC formats, complemented by a suite of built-in report generating functions. On-line reflectance color analysis is also provided, including Chromaticity and Color Difference.
