Introduction: Blue light hazard Lb (mW/m2/sr), safe allowable exposure time (S), hazard level (retinal blue light hazard parameters, maximum exposure time, BER and other related parameters. The blue light hazard weighted irradiance calculation method conforms to EN62471, GBT201452006 standards The hazard assessment of medium blue light hazard and small light source.It is specially designed for the inspection, testing and evaluation of blue light hazard and flicker hazard in children's eye protection desk lamp, primary and secondary school campus lighting detection. The flicker index refers to the area above the average value of the light output in a period accounting for the total area of the light output. Flicker Index [Flicker Index=Q1/(Q1+Q2)] Stroboscopic effect: that is, the negative effect of electric light source stroboscopic on human vision. The greater the strobe depth, the greater the negative effect and the more serious the harm. Features: 1. Adopt advanced miniature spectrometer technology, which has higher test accuracy than traditional probes; 2. Equipped with computer software, which can be connected to the computer to print the test report; 3. Color liquid crystal display, good graphic and text interface, can display spectral waveform, color tolerance ellipse; 4. The sensor adopts high-precision CCD; Continuous working time: equipped with 4000mA high-capacity lithium battery, which can be used continuously for more than 20 hours on a single charge; Integrate measurement functions such as spectrum, illuminance, and chromaticity; Technical parameter: Computer connection: USB Spectroscopic mode: telephoto bifurcation asymmetric CT spectroscopic system; Spectral bandwidth (FWHM): 2nm; Screen size: 5.0 IPS high-definition color LCD touch screen; Illuminance test range: 1-2000000Lux resolution 1Lux; Wavelength measurement range: 380nm-780nm; Wavelength accuracy: ±0.5nm Chromaticity coordinate accuracy: ±0.0025, resolution: 0.0001;; Correlated color temperature measurement range: 1000-100000K: Resolution: 1K; Color rendering index measurement range: R1 ~ R15 Total color difference accuracy: within ±0.2 (measurement conditions: under standard A light source); Storage capacity: Standard 8G large-capacity data storage card, data storage capacity of more than 30,000;
