Accurate measurement of LED characteristics become increasingly important. HP**0 LED Luminous Intensity Distribution Meter is based on CIE issued Publication No. **7 for measuring the optical properties of LEDs. Be specially used to measure relevant parameters of luminous intensity, intensity distribution, spread angle of light beam and electrical characteristics. Measures: Forward Voltage(VF), Reverse Current(IR), Luminous Intensity(IV), Intensity Angle(2θ1/2), Misalignment Angle(Δθ), Equivalent Luminous Flux(ΦEV), Luminous Intensity Distribution Features: 1. Automatically draw luminous intensity distribution curve 2. To set and control the process by PC and generate test report automatically 3. Built-in adjustable DC constant current power supply 4. The compatible software has the function of analyzing relationships between forward voltage and luminous intensity 5. Friendly graphic user interface provides an easy-to-use operation environment 6. The compatible software offers calibration function with LED standard light source conveniently. 7. Meets recommended geometry from CIE Pub. No. **7 Condition A Specifications: 1. Forward Current IF: 0.1mA ~ **0.0mA (±0.5%) 2. Reverse Current IR: 0.1μA ~ **0.0μA (±1%) 3. Forward Voltage VF: 0.1V ~ *0.0V 4. Luminous Intensity IV: *0.0mcd ~ **0.0cd (±8%) 5. Equivalent Luminous Flux(ΦEV): 0.**1lm ~ **0.0lm 6. Intensity Angle 2(θ1/2): **0°~ **0° (0.1°) 7. Sampling Interval: 0.1°/ 0.5° / 1°/ 1.5° Be measured at distances of **6mm (Condition A)
