Hioki TM6102 - Illuminance Meter

Accurately Measure Centroid Wavelength and Optical Power

RGB Centroid Wavelength Measurement Resolution: 0.01 nm Chromaticity (x, y) Coordinate Output Resolution: 0.00001.

The Discrete Centroid Wavelength Method for Laser Photometry

Achieve accurate laser photometry with real-time measurement of centroid wavelength and optical power.

1. Separate incident light into each RGB wavelength using optical devices
2. Simultaneously measure centroid wavelength (minimum resolution: 0.01 nm) and optical power (radiometric) quantity) for RGB wavelengths
3. Calculate chromaticity and photometric quantity using color matching functions (2°, 10°)
4. Simultaneously output a total of 11 optical properties

Approximation Limit for Color Matching Functions

Normally, tristimulus and other colorimeters use a combination of optical filters to approximate color matching functions. However, there are limitations to the degree to which optical filters (physical filters) can approximate color matching functions. Since the spectral width of a monochromatic laser is extremely narrow, both the approximation error for the color matching function and the variability inherent in the filter (individual differences) appear as differences in the measured values.

White Balance Adjustment Assistance Function Indicates the Optimum Route

Make adjustments to the target color (chromaticity) and brightness (photometric quantity) simply by matching the radiometric quantities for RGB with the specified ranges. Simultaneously adjusting chromaticity and photometric quantity, which is difficult with the conventional tristimulus method, greatly reduces balance adjustment work. This unique adjustment navigation function from HIOKI links with target values within tolerance (upper and lower limits) to automatically set the adjustment range.

Built-in Physical Quantity Correction Function to Minimize Differences between Instruments

Two physical quantity correction functions are built-in: centroid wavelength offset correction and radiometric quantity gain correction. Correction is applied according to the user's standard light source, minimizing any differences between instruments when multiple units are used. This is one of the major features of the discrete centroid wavelength method, which is not influenced by optical filters. This function is indispensable when making white balance adjustments in demanding conditions.

Delivering the Measurement Reliability Required for Uniform Evaluations

Precise Irradiance Evaluation Using Laser Light Sources
An all-new calibration environment was developed for this new RGB laser optical measurement instrument. This allows highly precise evaluations of RGB lasers with not only optical power meters but also illuminometers and luminance meters. Accurate laser measurement is guaranteed, providing highly reliable measurements that can be traced to national standards.

Reliable Incident Light Properties  *TM6102

Low Incidence Angle Dependence Essential for Ultrashort Focus Projector Evaluation
Chromaticity measurement that is not affected by the angle of incidence is required to measure the illuminance of a projector. Low dependency on the angle of incidence is an important property in order to evaluate products with a large angle of incidence in particular, such as ultrashort focus projectors. Further, since the oblique incident light properties of the RGB LASER ILLUMINANCE METER TM6102 are similar to the cosine law for the angle of incidence, it can be used in the same manner as a conventional illuminometer.

Low Reflection Paint to Minimize the Influence of Irregular Reflections
All parts around the light entrance are coated in a special low reflection paint so that measurements will not be affected by light reflecting off of the instrument. This keeps reflected light to a minimum and improves the instrument’s reliability.
