Operating Precautions
1.1 Product Overview and Features
This section describes the principles by which the Model TM6101 measures light and color.
The instrument’s light detector consists of diffusion optics that diffuse incident light and a series of optical sensors that detect the diffused light. The optical sensors detect light by separating the diffused incident light into 16 wavelength regions in the visible spectrum. The characteristics of the 16 optical
sensors have been precisely measured with a spectroscope, and correction coefficients that
approximate the color matching function have been calculated.
Chromaticity and illuminance are calculated from the strength of the light detected with the 16 optical
sensors and the correction coefficients. The sensors use measurement photodiode arrays and microcurrent measurement technology to deliver a high signal-to-noise ratio and high dynamic range.
Illuminance measured with the instrument is calibrated with a luminous intensity standard lamp and
HIOKI standard illuminometer
*1
, while chromaticity is calibrated with a spectral irradiance standard
lamp
*2
.
*1: The standard illuminometer is calibrated by a calibration facility.
*2: The spectral illuminance of the spectral irradiance standard lamp is calibrated by a calibration facility.
High-speed, high-precision measurement of LED light
•
The integration time can be set as low as 0.1 ms
• Instrumental error can be corrected using the reference value correction function
• Low incident angle dependence enables illuminance measurement, CIE averaged LED intensity measurement,
and light and color measurement while the instrument is attached to an integration sphere.
