HT-NCT-3 Glasses intelligent detector, transmittance for Glasses
HT - NCT - type 3 glasses intelligent detector is an ideal instrument to detect glasses performance.Principle of using grating spectrometer, ultraviolet, visible light spectrum is divided into monochromatic light, in 280 ~ 780 nm automatically measure the light transmittance, the average transmittance, color limit and traffic signal transmission ratio in accord with QB2457-99 and QB2506-2001 physical performance indicators of compulsory standards.Glasses intelligent detector is direct reading type intelligent instrument, is a high-tech products, high measurement accuracy, test speed, simple operation, easy to use, apply to the special purpose of sunshades, light color glasses and light (skiing, beach, mountain climbing, etc.) performance test of glasses.Full compliance with QB2457-99 test method and QB2506-2001 standard requirements.The instrument with microcomputer, the man-machine dialogue friendly interface, simple operation, complete function, can be widely applied optics research, production, teaching, etc, is an essential part of product quality inspection and supervision department analysis instrument.
1.Working principle of the instrument
HT - NCT - 3 glasses intelligent detector is one type of the source after grating spectrometer, ultraviolet, visible spectrum through monochromator filter, then through the slit and collimating light pipe will scan spectrum respectively through the test samples after exposure to the photoelectric sensor, optical signals into electrical signals, then analog to digital quantity, via the RS - 232 - c serial port into the microcomputer processing, automatic measure the light transmittance, the average transmittance, traffic signal of color coordinates x, y, yy.Xg, yg and average sunlight (D65) color coordinates xs, ys and lens traffic signal transmission thanτsigR,τsigY,τsigG all quantitative performance indicators, etc.
