Pro-Lite has launched the CL-200a, an illuminance colorimeter from Konica Minolta that provides accurate lux, CCT, chromaticity and dominant wavelength measurements - even with LEDs.
The CL-200a features a cosine diffused sensor head based on three detectors with filters that are precision matched to the CIE tristimulus colour-matching functions.
This means that the CL-200a will give accurate readings, regardless of the type of light source under test.
The CL-200a is a battery-operated, handheld photometer that reports illuminance in lux, CIE tristimulus values (XYZ), CIE chromaticity (xy, u'v') and correlated colour temperature (CCT, Kelvin).
It also reports dominant wavelength and purity, metrics that are commonly used to express the colour of LEDs.
The CL-200a incorporates a USB interface port as standard and is supplied with PC application software, which allows the operator to log illuminance and colour readings automatically to an Excel spreadsheet.
The CL-200a is available with an accessory kit that allows the operator to separate the sensor head from the body of the sensor.
This option means that the sensor head can be placed directly at the surface upon which illuminance measurements are required to be made at, while the operator can stand to one side while recording the light level.
The CL-200a is the colorimeter version of the existing T-10 photometer, which is said to provide a more affordable alternative if colour measurements are not required.
