Konica Minolta Launches a New Compact, Easy to Use CRI Illuminance Meter

The CRI Illuminance meter CL-70F is a compact, lightweight, handheld entry-level instrument for measuring the colour and illuminance of light sources (including new LED and EL light sources). Measurement data is displayed in terms of CRI, tristimulus values, illuminance, chromaticity, dominant wavelength, excitation purity, correlated colour temperature, and difference values from a target.

Main Features:
•    Spectral sensor with a measuring range of  380 nm ~ 780 nm
•    Measure Color Rendering Index (CRI) with a comprehensive color bar graph
•    Compact, easy to carry and battery operated
•    Colour touch screen for graphical and numerical display of measurements

The sleek instrument is designed for a variety of common lighting tasks including lighting design and ongoing maintenance. Providing spectral information and CRI measurement the CL-70F provides entry level access to cutting edge light measurement features. Combining the instrument with a flash sync cable enables spectral measurements of flash light making the CL-70F a powerful tool for professional imaging and entertainment markets.

CRI measurement:
The CL-70F provides easy access to CRI measurement data. The display shows the Ra value including all individual indices (R1 to R15) in a simple bar graph. For further information on Colour Rendering please see our light measurement resource : The Language of Light.

Easy measurement of correlated color temperature (Tcp):
The CL-70F can measure correlated color temperature and the difference from the blackbody locus Δuv, values which are often used to describe the color of light sources. The colour temperature of light is defined as the absolute temperature (in Kelvin) at which a blackbody would emit that particular color of light. The colours of light emitted by a blackbody at various temperatures can be plotted on a curve which is called the "blackbody locus". Since the output of many light sources do not lie directly on the blackbody locus, "correlated colour temperature" is used to describe their colours.

Easy Zero-adjustment without a receptor cap:
Slide the ring on the diffusor counterclockwise to perform dark calibration.

Additional features provided by included Utility software CL-SU1w:
With the software CL-SU1w which is included as a standard accessory, you can modify instrument settings, store & group data and make further analysis of the measured data.

The CRI Illuminance Meter perfectly fits into the range of compact handheld Light Measuring instruments between the colorimeter model CL-200A and the high precision spectrometer CL-500A.
