SEKONIC C-7000 FEATURES

Measurement capabilities for various light sources
(LED, organic EL, HMI, fluorescent light, tungsten light, natural light, flash light, etc.)The C-7000 uses a CMOS linear image sensor in the light receiving section. Spectroscopic measurement is performed in the wavelength range of 380nm to 780nm to obtain an accurate color temperature.

It can accurately measure not only conventionally used flash light and constant light sources (fluorescent light, tungsten light, HMI, etc.), but also light sources such as LEDs and organic ELs, which have been increasing in recent years.

Original optical design for the light receiving partSpectrometer C-7000 makes full use of optical technology in the light receiving part. We remove infrared rays that are not necessary for measurement and adjust the angle of light. In addition to the use of a dedicated CMOS linear image sensor, a unique optical system minimizes measurement errors caused by oblique incident light. It also incorporates a newly developed thin dark correction unit and ND filter. Dark calibration and high-intensity flash measurement can be switched simply by rotating the light selection ring.

Various display modesIn addition to the text mode that displays measured values numerically and the spectrum mode that displays the wavelength of the light source, various display modes such as CRI mode, 5 color rendering evaluation modes, chromaticity diagram mode (CIE1931, CIE1976), chromaticity diagram comparison mode (CIE1931, CIE1976), etc. are available.
