1 high precision. High stability in spectrum measuring. spectrum analyzer. 2 simple and convenient software-operations with more personality, Chinese panel 3 Lineal CCD data-collecting 4 2048 data-collecting point, providing stable optics parameter 5 binary optics sampling by imaging in the tens 6 4 quadrants precise source output. providing precise testing electric current and voltage 7 16 digital high precision A/D collecting card with more precise testing data 8 materials from the same group can be put into use without emendation 9 large-scale material-grouping（φ1.5-φ10料） 10 optics track IS, electricity track KEITHLEY 性能卓越的LED分光机(LED Lamp testing & sorting machine with superexcellent performance) 1 with Chinese panel, it can be easily controlled by both man and machines .According to the practical requirement, various controlling parameters can be adjusted and assembled to meet the optimizing need for production. 2 LED of various sizes and sorts can be transmitted by the high quality feeding system in a quick, stable, and reliable way with the highest speed of 20k/h 3 Using import fiber spectrum analyzing card, double detecting heads 4 The brightness (15mcd-100000mcd), wavelength, color temperature, spectrum power, color purity, peak length can be measured accurately. 5 In light of various demand of the customers, it can provide reliable testing data with high efficiency 6 Using the most advanced high-speed spectrum imaging system. 7 Gathering the optic signal in a enclosed way can minimum the interference from brightness 8 With the given optimized design, HWL-series has quick and sensitive spectrum response. By the advanced fiber spectrum instrument, the machines?spectrum distinguishing rate reached 0.02nm; its testing speed is as fast as 13k/h. 9 By the advanced spectrum physical testing and analyzing means, LED lamb testing & sorting machine of HWL series can class light and color in high speed and precision. Its edge over other machines is it overcome the hurdling problem that the testing and classing of the off-color LED of the white light LED by other machines of the same kind is not precise and reached the criterion that?everything is not slight enough to be not detected by this pair of sharp eyes?
