With the overwhelming popularity of new light sources such as advanced LED and Organic Electroluminescence, the need to understand, manage and control these sophisticated illumination systems is essential. Manufacturing quality and processes along with varying color and illumination qualities can often result in consistency issues. To address these lighting challenges, Sekonic has created the C-7000 to offer advanced precision lighting control for the Photo, Video, and Cine industries.
Information screens such as Correlated Color Temperature, Illuminance, Color Rendering Index (CRI), Tristimulus Value, Chromaticity Coordinates (for CIE1931/CIE1964 & CIE1976 standards), Peak Wavelength, Excitation Purity and Photosynthetic Photon Flux Density, and more are displayed on the 4.3" color touch screen display. The enhanced measurement data and display modes of the C-7000 provide the information that is widely utilized in light fixture manufacturing and quality control, as well as monitoring illumination of offices, roadways, and public facilities to meet government lighting standards. Indoor agricultural lighting, precision medical light control and many more lighting industries will find the C-7000 of particular usefulness in their daily application to meet requirements for lighting control.
The C-7000 is also computer-friendly. Connect the C-7000 to a Windows-based PC and users will be able to make meter settings with the C-7000 Utility (included with the meter) and output CSV format files of measurement data in 1 nanometer (nm) wavelength increments from 380 to 780nm. Additionally, graphs of spectral distribution, CRI, and chromaticity diagrams for CIE 1931(1964) and CIE1976 color spaces can be outputted as well. With the C-7000 Utility software, output of memorized data is provided at every 1nm(nanometer) increments in CSV format. The C-7000 can be utilized to measure data for light manufactures quality control, medical facilities, educational / office safety and health standards, agricultural lighting / design and many more industrial uses.
