Advantages of LCD Optical Measurement System

The main functions of the LCD optical measurement system are as follows:

The luminous flux, luminous efficiency, optical power, relative spectral power distribution, color coordinates, color temperature, main wavelength, peak wavelength, spectral half-width, color rendering index, color purity, red ratio, color tolerance, forward voltage, forward current, reverse voltage, reverse current and other parameters of packaged LCD were tested. It can simultaneously measure the transient optical properties (pulse measurement) and steady optical properties (DC measurement) of LCD.


Technical advantages of the LCD optical measurement system:

1. Low stray light

The stray can be less than one-tenth of the original high-precision fast spectrometer by improving the designed high-precision grating with high matching and the scientific-grade refrigeration array detector, and using BWCT technology and modified NIST stray light correction technology.

2. Wide linear dynamic measurement range

Compared with conventional array detectors, the scientific level array detectors in LCD optical measurement system have a wider linear dynamic range, and the dynamic range of the instrument is further widened after the optical matching modification design.

3. Fast

LCD optical measurement system can not only measure the steady-state characteristics of light sources but also their transient optical properties, which fully meet the requirements of relevant standards. Within the sensitivity range of the instrument, no matter how fast the transient pulse of the measured light is (e.g. less than a microsecond), the instrument can achieve fast full spectrum measurement by synchronous triggering function. The system also uses a scientific-level array detector instead of a mechanical scanning system, which can complete the accurate measurement of the whole spectrum in a very short measuring time (millisecond level).

4. High Precision

Designed for high precision applications, the world's top commercial scientific refrigeration array detectors and precision gratings are improved to make them more matched and then equipped with precise optical systems and electronic circuits. The whole system can achieve high resolution, high sensitivity, low noise, low stray light, and wide dynamic range, thus achieving the purpose of accurate measurement.


5. High repeatability and stability

The instrument does not have a scanning mechanism of mechanical movement, and the only temperature factor that will change with the environment is controlled by constant temperature refrigeration technology to the level of (+0.05). The repeatability and stability of the measurement are high.
