GO-NR1000 Near-field Goniophotometer
Near-field photometric measurement,establishing the Ray model of light via algorithm
Makes it more convenient & accurate to do the secondary optical design & development
Typical application scenarios
Suitable for LED light source, LED chip, module and other small light source, the principal function includes: spatial light intensity distribution curve, spatial color distribution curve, iso-lux curve, total luminous flux, effective luminous flux, spatial luminance curve, etc.
The test data can be saved as IESNA (*.ies), CIBSE (*.cib), EULUMDAT (*.ldt), CIE (*.cie), CEN (*.cen) and other formats, which can be directly used as the input data of international general lighting design software.
Spatial luminance data can be imported into near-field lighting generation software to generate light data that can be imported into third parties (TracePro and LightTools).
Main characteristics
1. For Secondary Optical Design & Development of Light Source
The near-field goniophtometer uses the imaging luminance colorimeter based on 2D CCD as the detection element to measure and record the luminance distribution of the light source in all directions, that is, the luminous flux of each luminous point on the light source in all directions, and then establishes the actual light distribution model of the light source to be measured. The model can be input into the optical design software to carry out the light distribution design of the luminaries and the lighting site design.
2. Accurate Angle Positioning
By adjusting the precise position and angle of the light source, the problem of poor measurement accuracy can be effectively overcome when the traditional goniophotometer measures the light source at a long distance and the LED module composed of multiple LEDs with a certain beam angle.
3. Real Ray Model for the Accurate Optical Design
GO-NR1000 can be used as a sample to establish a real light model, which can provide more detailed data for optical design.
