Each parameter is displayed in both digital and bargraph form, with the ability to carry out automatic 'go/no-go' evaluation on the basis of pre-programmed criteria.
The tests carried out by the 3298 could previously be made only on very expensive dedicated optical instrumentation.
The low-cost design of the 3298 makes it practicable to expand this type of quality measurement for applications in development and manufacturing environments.
The 3298 is available in two versions for monochrome and colour displays, respectively.
The measurable range of luminance is from 0.01 to 40,000cd/m2, while flicker measurement ranges are from 2 to 20% RMS with an accuracy of +/-1%.
The instrument incorporates a built-in programmable lowpass filter for flicker measurement.
The colour version has an accuracy of chromaticity measurement of +/-0.002 for a Type A standard light source.
The compact, lightweight instrument comprises separate sensor and display units, and may be battery operated for portable use.
