Measurement Principle of the CM-700d Spectrophotometer
The CM-700d utilizes a d/8° geometry integrating sphere with dual pulsed xenon flash lamps that illuminate the sphere's Spectralon-coated inner surface. The sample receives uniform diffuse illumination, and a detector positioned at 8° from the surface normal collects the reflected light. A diffraction grating disperses the light across a 35-element photodiode array to generate a spectral reflectance curve from 360 nm to 740 nm. The double-beam system references the lamp output against the sphere wall for drift compensation, ensuring consistent accuracy over thousands of measurements.
